Instructions for Authors


Preparation of the manuscript


   Submission Formats

Manuscripts must be sent on OJS simultaneously in two formats with line numbering: Word or LaTeX and PDF format.

If you submit a Word format, please number the lines of your file before exporting it into PDF (PDF shall also have lines numbered).

To number the lines, go to the Layout tab of your document (in the Page Setup group) and click on Line Numbers / Continuous.

To know more about the operation, pleas visit the support office page.

If you forgot files during your initial submission :

  • if the missing files are numerous and / or significantly change the content of the submission: it would be better to abandon the initial submission and make a new submission
  • otherwise: you can open a discussion with the editor, attach the missing file(s) and ask the editor to add them


   General information for Word and LaTeX formats

Word Formats
  • It is important that the file be saved in the native format of the word processor used.
  • The text should be in single-column format. Keep the layout of the text as simple as possible.
  • Most formatting codes will be removed and replaced on processing the article.
  • In particular, do not use the word processor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts etc.
  • When preparing tables, if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs, not spaces, to align columns.
  • Note that source files of figures, tables and text graphics will be required whether or not you embed your figures in the text.
  • Please note that the paper submitted must be written in a correct language. Any article received in an approximate English or French will be refused immediately. Authors have the possibility to turn to automatic correctors, DeepL type.
  • Note that every accepted article will be converted into LaTeX format for publication.
LaTeX Formats

Authors are invited to prepare their article with PDFLaTeX (for submission or after acceptance), the bibliographic references stored in a bibtex file, illustrations preferably as PDF, with a sufficient quality for unambiguous Web display or print. Authors are strongly encouraged to use the journal's LaTeX class file and bibtex style, but amsart or smfart classes, as well as amsplain and smfplain styles are accepted. Please refer to the instruction page for papers prepared with LaTeX (under construction).


Composition recommendations



Contributions can be written in English or in French. Articles written in French must include English translations for Title / Abtract / Keywords. French translation of Title / Abtract / Keywords is optional for articles written in English.

If English or French is not your native language, you may want to have your manuscript edited by a native speaker or use a professional language editing service. It is likely to accelerate the editorial process. A deficient linguistic quality may justify a rejection decision.


   Presentation of the manuscript

Manuscripts should include, in the following sequence:

1) the title (short, but explicit)
Avoid abbreviations and formulae where possible

2) the name of all authors
Please clearly indicate the given name(s) and family name(s) of each author and check that all names are accurately spelled. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower- case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author.

Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication (the name of the author to whom correspondence and proofs are to be sent must be followed by an asterisk). This responsibility includes answering any future queries about Methodology and Materials. Ensure that the e-mail address is given and that contact details are kept up to date by the corresponding author.

3) the complete professional address of all authors (including e-mail address)

  • PLEASE NOTE: all e-mail addresses must be entered during Step 3. ‘Enter Metadata’ of the online submission process

4) the abstract (100 words max.)

An abstract is often presented separately from the article, so it must be able to stand alone. For this reason, References should be avoided, but if essential, then cite the author(s) and year(s). Also, non-standard or uncommon abbreviations should be avoided, but if essential they must be defined at their first mention in the abstract itself.

5) keywords (a maximum of 7, at least 5)

Provide keywords using American spelling and avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations: only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.

If the article is written in English but contains an abstract in French, keywords in French are mandatory.

6) the text of the article must be typed, double spaced and each page must be numbered.
Divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ...), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to 'the text'. Any subsection may be given a brief heading. Each heading should appear on its own separate line.

7) the reference number of any deposited supplementary material along with any appropriate acknowledgements (maximum 3 lines)

8) references, captions, tables, figures.


   Optional information

  • Acknowledgements: Collate acknowledgements in a separate section at the end of the article before the references and do not, therefore, include them on the title page, as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., providing language help, writing assistance or proof reading the article, etc.).
  • Dedication: a one-sentence dedication of the article may be included as a separate paragraph after the "Acknowledgements" section.
  • Formatting of funding sources: list funding sources in this standard way to facilitate compliance to funder's requirements:
    Funding: This work was supported by the National Institutes of Health [grant numbers xxxx, yyyy]; the Bill & Melinda Gates Foundation, Seattle, WA [grant number zzzz]; and the United States Institutes of Peace [grant number aaaa].
    It is not necessary to include detailed descriptions on the program or type of grants and awards. When funding is from a block grant or other resources available to a university, college, or other research institution, submit the name of the institute or organization that provided the funding.
  • Appendices: if there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1) and so on. Similarly for tables and figures: Table A.1; Fig. A.1, etc.

  • Footnotes: footnotes should be used sparingly. Number them consecutively throughout the article. Many word processors can build footnotes into the text, and this feature may be used. Otherwise, please indicate the position of footnotes in the text and list the footnotes themselves separately at the end of the article. Do not include footnotes in the Reference list.



They must be numbered in square brackets and listed sequentially as they appear in the text (autotext, field, bookmark, caption, cross-reference, etc.). Do not use automatic insertion for references and articles. All entries in the reference list must correspond to references in the text and vice versa. References must be noted in the text by a number enclosed in square brackets. The titles of journals should be abbreviated according to international rules[1]. Bold and italic characters should not be used in the reference list (please note that there is later formatting by the publisher so that examples below are not identical to the final published format).

Examples are given below of the layout to be used in the reference list.

  • Article (all authors must be mentioned):
    [1] B. Cage, F.A. Cotton, N.S. Dalal, E.A. Hillard, B. Rakvin, C.M. Ramsey, C. R. Chimie 6 (2003) 39.
  • Book:
    [2] P. Braunstein, L.A. Oro, P.R. Raithby (Eds.), Metal Clusters in Chemistry, Wiley-VCH, Weinheim, Germany, 1999, Vols. 1–3.
  • Chapter in a book:
    [3] P.W. Jolly, G. Wilke, in: B. Cornils, W.A. Herrmann (Eds.), Applied Homogenous Catalysis with Organic Compounds 2, Wiley-VCH, Weinheim, 1996, p. 1024.
  • Multiple references under the same number:
    [4] (a) N. Giuseppone, J.-M. Lehn, J. Am. Chem. Soc. 126 (2004) 11448; (b) D.J. Tantillo, R. Hoffmann, Eur. J. Org. Chem. (2004) 273.


   Math formulae

Please submit math equations as editable text and not as images. Present simple formulae in line with normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y. In principle, variables are to be presented in italics. Powers of e are often more conveniently denoted by exp. Number consecutively any equations that have to be displayed separately from the text (if referred to explicitly in the text).


   Figures and illustrations

General points

All illustrations should be labelled as figures (and/or schemes) and numbered using Arabic numerals. Original documents or photographs should be provided for reproduction of the figures.
• Make sure you use uniform lettering and sizing of your original artwork.
• Embed the used fonts if the application provides that option.
• Aim to use the following fonts in your illustrations: Arial, Courier, Times New Roman, Symbol, or use fonts that look similar.
• Number the illustrations according to their sequence in the text.
• Use a logical naming convention for your artwork files.
• Provide captions to illustrations separately.
• Size the illustrations close to the desired dimensions of the published version.
• Submit each illustration as a separate file.

Whenever possible, figures should be submitted in their desired final size, i.e. 75 mm wide. In cases where they cannot be avoided, double column figures should not exceed 160 mm in width. No original document should exceed A4 size (21 × 29.7 cm). Photographs and half-tones should contain good contrast.

  • In reaction diagrams, the principal reagents and experimental conditions should be given above an arrow within the scheme, rather than as a caption.
  • Figures and structural formulae will not be redrawn; they may be inserted into the text but should also be provided on separate sheets at the end of the manuscript. They should be of high enough quality to allow direct reproduction.
  • Units and symbols should be consistent with those in other diagrams and the text. Follow internationally accepted rules and conventions: use the international system of units (SI).
  • Characters should be large enough to be legible after a possible reduction of 70%. The Helvetica typeface is preferred for text appearing within figures.
  • Diagrame, wherever possible, should be prepared using ChemDraw™ using the following preferences: chain angle = 120°, bond spacing 19% of length, fixed bond length = 0.6, text settings = Helvetica size 10.


The illustrations (figures, schemes...) should be saved in TIFF (minimum 400 dpi resolution), EPS, ChemDraw or Adobe Illustrator formats. EPS format is not suitable for text-containing files. Figures in Word format cannot be used.

Wherever possible, diagrams should be prepared using ChemDraw using the following preferences: chain angle = 120, bond spacing 19% of length, fixed bond length = 0.6, text settings = Helvetica size 10.

Color artwork

  • Preferable formats are PNG, TIFF or high-definition JPEG, EPS (inappropriate if figure contains text), Adobe Photoshop or Illustrator.
  • Avoid Power Point documents.
  • Figures must be supplied separately, in their source file, and in no instance incorporated in case of a text file.
  • Minimum resolution: 400 dpi.
  • Maximum size onf each file: 50 MB.



They should be numbered using Roman numbers and should appear in numerical order in the text. There should be no vertical lines in the tables. A caption is required for each table.

   Conventions and abbreviations

They should be defined in brackets after their first mention in the text. Internationally accepted units and nomenclature must be used (ISO 31 and ISO 1000). Standard units of measurement and chemical symbols for elements may be used without definition in the manuscript.

   Crystallographic data

Manuscripts reporting crystal structures determined by X-ray diffraction should include a list of the main bond lengths and angles. ORTEP drawings (except for stereochemical diagrams) are also required (but can be placed in the Supporting information if other software is used to prepare the view of the structure appearing in the text).

Before submission of a manuscript to C. R. Chimie, the correspondence author must have obtained the Checkcif report for each structure (free online Checkcif service provided by the International Union of Crystallography: http://journals.iucr.org/services/cif/checkcif.html.

He should then deposit the crystal structure(s) in .cif format with the Cambridge Crystallographic Data Centre (CCDC) in Cambridge, UK, for structures containing at least one carbon atom, with the Fachinformationzentrum (FIZ) in Karlsruhe, Germany, for other structures. Do not submit the cif files with your manuscript, but the PDF of the Checkcif report.

These data can be obtained free of charge from The Cambridge Crystallographic Data Centre via www.ccdc.cam.ac.uk/data_request.cif  /Fachinformationzentrum Karlsruhe, D-76344 Eggenstein-Leopoldshafen, Germany, on quoting the depository number(s) CSD-...

   Supporting information

A manuscript may include electronic Supporting Information, which will be accessible only on the WWW. Authors must keep a copy to make available to readers who do not have access to the Internet. As this material [text, tables, schemes, figures but not the crystallographic (CIF) data, see above] undergoes the peer review process, it must be included and clearly marked as “Supporting Information to be published electronically”, when the paper is submitted. In order to ensure that your material is directly usable, please provide the file with a maximum of 50 MB per file.

A standard text will be added in the printed version:

† Supporting information for this article is available on the WWW under http://www.xxxxx or from the author.
