Crystallography Open Database (COD)

Crystallography Open Database (COD) is an open-access database of crystal structures of organic, inorganic, and organometallic compounds other than biopolymers.  COD also contains information on minerals. COD contains approximately 500,000 structures as of February 2023. Candidates can be narrowed down by chemical formula, composition, space group, etc. Users can also obtain information on material structures, CIF files, and literature information. For organic molecules, it is also possible to search by the structural formula. All available structural data is in the public domain.
