Cambridge Structural Database


  CSD Enterprise Components     

Established in 1965 by the Cambridge Crystallographic Data Centre (CCDC), the Cambridge Structural Database (CSD) is the world’s repository for small-molecule organic and metal-organic crystal structures. Containing over 900,000 entries from x-ray and neutron diffraction analyses, this unique database of accurate 3D structures has become an essential resource to scientists around the world. The June 2015 issue of CCDC's Crystalline Newsletter covers 50 Years of Sharing Crystal Structures (PDF).  In addition to coverage of the published literature, CSD searches also contains data published directly through the CSD as CSD Communications that are not available anywhere else.
