Cambridge Structural Database
Cambridge Structural Database (CSD) contains crystal structure information for over 245,000 organic and metal organic compounds. All of these crystal structures have been analysed using X-ray or neutron diffraction techniques. For each crystallographic entry in the CSD there are three distinct types of information stored. These are conveniently categorised in terms of their "dimensionality": bibliographic information, chemical connectivity, 3D Molecular Structure, and 3D Crystal Structure. The web version provides a full range of text/numeric search options, in addition to more complex search functionality, including: substructure searching,and reduced cell searching, similarity searching.
Note: This version supercedes the cd-rom version.
