We are delighted to announce the release of the February 2017 update of the Cambridge Structural Database (CSD). With 18,092 new entries, this update brings the total size of the CSD to over 876,000 entries.

The data update includes 2,284 entries that have been published directly through the CSD as a CSD Communication. This takes the number of CSD Communications published in 2016 alone to over 4,400, which is a new record and demonstrates how keen the community are working to share more of their data. This includes Iomeprol, a contrast medium for medical imaging, that has been added to the CSD in three polymorphic forms (CSD refcode: EYUPUL, DOI: 10.5517/ccdc.csd.cczz1kj, CSD refcode: EYUPUL01 DOI: 10.5517/ccdc.csd.cczz1jh and CSD refcode: EYUPUL02, DOI: 10.5517/ccdc.csd.cczz1hg).

As a part of this data update we have also updated our subsets of Metal-Organic Framework (MOF) structures with thousands of additional entries, reaching a total of 79,526 entries for the main MOF subset. An example of a new addition to the subset is the first CSD structure of a Zr(IV)-based MOF with polybenzene (pbz) topology, (CSD refcode: IXETEM, DOI: 10.5517/ccdc.csd.cc1m8m8s).

Installing the updates

The CSD software suites have a built-in auto-update mechanism that makes updating the data and software easy, and will also notify you if an update is available. More information is available via our Support section

If you would prefer to download and install an update manually, then all of our updates are also made available via the 'Data & Software Updates' section of our Downloads page.
