Cambridge Structural Database (CSD)

CSD is the world'€™s leading repository of small organic and metal-organic crystal structures with over 500,000 x-ray and neutron diffraction analyses.

Each crystal structure is validated and crosschecked by leading chemists and crystallographers to ensure the highest possible standards. New entries are added on a regular basis. USC subscribes both to the online web version and desktop version for Windows, Mac OS, and Linux. The majority of users will be best served by using the web version of CSD, but if your research requires an offline, desktop version of CSD, please contact the Science and Engineering Librarian for Chemistry for more information.
