The CCDC allows you to publish data directly through the Cambridge Structural Database (CSD) as a CSD Communication. Over 43,000 structures have been published this way since 1976.

By publishing in the CSD knowledge and insights can be drawn from the collective data, this is used to discover new drugs, develop new materials, and understand fundamental chemistry - see how people use the CSD in our case studies.

Depositions where no associated scientific article is envisaged but that the depositor would like to share through the CSD are referred to as CSD Communications (formerly known as Private Communications) and will contain the author list supplied by the depositor. For recommendations on who should be included as an author please see our CIF Deposition Guidelines.


These resources present how to publish your data as CSD Communications and how to manage your structures via the My Structures portal.

  • CSD Communications

    Explore advantages and instructions of depositing your data as CSD Communications in these video and workshop.

    Watch the How to publish CSD Communications video on YouTube (watch here) and LabTube (watch here).

    Or follow the step-by-step workshop (Chinese and English text) based on the video script (download it here).

  • My Structures

    This how-to video presents how to update and publish your crystal structures through My Structures portal. Video available on YouTube (watch here).


Benefits of sharing data as a CSD Communication include the following:



A citable DOI allows you to receive credit for your structures and add the data to you ORCID record.

A journal ISSN (2631-9888) to make recording CSD Communications citations and publications more convenient for publishers and academic institutions.

If you would like to reference a CSD Communication then we would recommend using the following style of citation

“D.S.Cati, H.Stoeckli-Evans, CCDC 227635: CSD Communication, 2004, DOI: 10.5517/cc7mw2s”


Automatic linking via CCDC DOI from third-party repositories, such as DataCite, the Web of Science Data Citation Index and may also be linked from ChemSpider, PubChem and PDB Chemical Component Dictionary


Publish data through the deposition process and update details via the “MyStructures” User Portal

To deposit data directly with the CCDC via a CSD Communication please use our web-based CIF deposition and validation service at

To specify that the data should be deposited as a CSD Communication please select the CSD Communication button on the Add Publication step and add the full author list.

You are also able to publish previously deposited data directly through the CSD as a CSD Communication at any time after deposition. To do this you should log in and go to 'My Structures'. From the list of your deposited structures, any that have a status of 'Unpublished' have not been made accessible to the public or added to the CSD. If you would like to publish any of these structures as a CSD Communication click on the 'Details' button. You will then be shown a Details page, where you should check and confirm that the author names associated with the data are correct then press 'Publish as a CSD Communication' to publish your data.


Resulting CSD entry curated and enhanced by our scientific editors

As a CSD Communication will not have additional information available in a published paper, it is especially important for the depositor to include as much information as possible in the CIF with the crystal structure data. Information such as the modeling of disorder or experimental data (such as the compound's melting point) are not routinely added by refinement software, but will allow us to create a full and accurate database entry for the structure. For information on the data deposition process and information required please read our structure deposition or FAQ pages. The web deposition service also integrates the IUCr's checkCIF service which highlights issues with the refinement that may require further consideration. We may contact you regarding any queries arising during the editorial validation process.


Both free to publish and free to access through our Access Structures service.


Your data made instantly available to the world via Access Structures. Just 8 simple steps to deposit your data with us using our Deposit Structures service & for most structures only minutes from clicking Submit button to receiving the confirmation of a new or revised CCDC number for your compound.


Meets funder data policies in a recognized repository


Free long-term data preservation in a trusted repository, stored where you can access it from anywhere


Your data can be re-used by a wider community in different fields, to design drugs, new materials, etc.

Depositors of CSD Communications should be aware that a few journals will not accept papers which contain data that have previously been published in any form, including electronic publication on web pages or in a distributed database.
