The CCDC allows you to publish data directly through the CSD as a CSD Communication. Over 5,000 structures were published in this way in 2016 making CSD Communications the No. 1 place to publish crystal structures.

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 Private Communications to the Cambridge Structural Database (CSD)), and will contain the author list supplied by the depositor. This may include new data collections of structures that have been previously published, or structures with disorder or data collection problems that result in lower quality refinement statistics.

Recognition - A citable DOI allows you to receive credit for your structures.

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”

Discoverability - Automatic linking from third-party repositoiries

Ease - Publish data through the deposition process and 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 the data should be deposited as a CSD Communication please select the CSD Communication button on the Add Publication step of the deposition.

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 will need to register for an account on our website and then when you log in go to 'My Structures'. You will see a list of your deposited structures. Any that has a status of 'Unpublished' have not been made accessible to the public or added to the CSD.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 and you will need to press 'Publish as a CSD Communication' to publish your data. At this stage you should check and confirm the author names associated with the data are correct.  

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 modelling 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.

Integrity- Resulting CSD entry curated and enhanced by our scientific editors

Cost-free - Both free to create and free to access

Speed - Your data made instantly available to the world via Access Structures

Compliance- Meets funder data policies

Security - Free long-term data preservation in a trusted repository

Impact - Your data can be re-used to design drugs, 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.
