Cambridge Structural Database (WebCSD) This link opens in a new windowThe Cambridge Structural Database is the world's primary repository for small molecule crystal structures, providing access to bibliographic, chemical and crystallographic data for organic, organometallic and metallic compounds. 3D structures have been determined using X-ray and neutron diffraction. The database records results of single crystal and powder diffractions studies. The web version (WebCSD) provides access to data; interactive functionality requires installation of the desktop client.
