WebCSD - Cambridge Structural Crystallographic Database

The Cambridge Structural Database (CSD) is a highly curated and comprehensive resource.

Established in 1965, the CSD is the world’s repository for small-molecule organic and metal-organic crystal structures. Containing over 975,000 structures from x-ray and neutron diffraction analyses, this unique database of accurate 3D structures has become an essential resource to scientists around the world.

With comprehensive and fully retrospective coverage of the published literature you can have full confidence that your CSD searches are returning all crystal structure matches. The CSD also contains data published directly through the CSD as CSD Communications that are not available anywhere else.

Searchable by name, structure or molecular formula.
