Comprehensive of the published literature and highly curated, the Cambridge Structural Database (CSD) is an essential resource to scientists around the world
Established in 1965, the CSD is the world’s repository for small-molecule organic and metal-organic crystal structures. Containing over 850,000 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.
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 directly deposited data that are not available anywhere else.
Growth of the CSD since 1972, the red bar shows structures added annually.
Each crystal structure undergoes extensive validation and cross-checking by expert chemists and crystallographers to ensure that the CSD is maintained to the highest possible standards. Also, each database entry is enriched with bibliographic, chemical and physical property information, adding further value to the raw structural data. These editorial processes are vital for enabling scientists to interpret structures in a chemically meaningful way.
CSD Refcode TUWMOP - the 800,000th entry added to the CSD
The CSD is continually updated with new structures (>50,000 new structures each year) and with improvements to existing entries. With regular web-updates and early online access to newly published structures you can keep fully informed of the latest research.
