CSD Communications is a collection of small molecule crystallographic data which has been shared by depositors through the Cambridge Structural Database (CSD) without an associated scientific article.

This may include new data collections of novel structures or new determinations or re-refinements of previously published compounds. CSD Communications have an ISSN number and each entry contains the author list and crystallographer details as supplied by the depositor. This allows authors and data producers to get credit for their data, as their structure receives a full CCDC citation including DOI and publication year. The objective of CSD Communications is to help scientists contribute to the quantity of crystallographic data available to the public. So far CSD Communications have provided the scientific community with access to more than 40,000 crystallographic structures which may never have otherwise been made public.

More information about the benefits of CSD Communications is available here and we also have a series of blog posts about CSD Communications and data sharing in general if you want to learn more about this initiative.

You can explore the CSD Communications collection in the archive below or you can access the dataset directly with a CCDC Number or Data DOI from our Access Structures service


The CSD Communications archive contains all of the data published directly through the Cambridge Structural Database (CSD) by the Cambridge Crystallographic Data Centre (CCDC) as CSD Communications (previously known as Private Communications).
