CSD - Cambridge Structural Database

Databases

The CSD is the world’s largest database for small-molecule organic and metal-organic crystal structures, with more than 1 million curated entries from x-ray and neutron diffraction analyses.

The CSD covers all organic and metal-organic structures. Peptides and polysaccharides of up to 24 residues and mono-, di- and tri-nucleotides are included as well as boron compounds containing one or more B-H or B-OH bonds and borazines and ring compounds containing any two of the following elements: N, P, S, Se and Te.

Each structure within the CSD undergoes extensive validation and cross-checking via automated workflows and through manual curation by the CCDC. All the data is enriched with bibliographic, chemical and physical property information.

To access the full database, including all CSD software, you’ll need to download and install the CSD package. Instructions can be accessed here.  Alternatively, the limited web-version can be accessed by clicking “go to database”.

Detailed user guides and sometimes tutorials are available for all CSD software.
