Cambridge Structural Database is a repository of highly curated small-molecule organic and metal-organic crystal structures, which may be viewed in 3-D. It contains over 1 million entries from x-ray and neutron diffraction analyses, and approximately 50,000 structures are added per year. These new structures are deposited by researchers from around the world. Deposited structures are validated and enhanced with bibliographic, chemical, and physical property information.
