Cambridge Structural Database (CSD), from the Cambridge Crystallographic Data Centre (CCDC) is the world's largest repository, for small-molecule organic and metal-organic crystal structures, with more 800,000 entries from x-ray and neutron diffraction analyses. Along with data about the crystal structure, each entry includes chemical/physical property data and associated journal article reference.
UC San Diego faculty, staff and students can access CSD two ways:
If you only want to search and browse structures and view the associated chemical, crystallographic, and bibliographic information for those structures, WebCSD should be sufficient. If you want to use any of the programs listed below (including the 3D printing), you'll need the full CSDS.
CSDS includes the following programs, with detailed user guides and (in some cases) tutorials available for each
