ICSD (standing for Inorganic Crystal Structure Database) is a database of inorganic crystal structure data. It was founded in 1978 by Günter Bergerhoff (University of Bonn) and I.D.Brown (University of McMaster, Canada). It is now produced by FIZ Karlsruhe in Europe and the U.S. National Institute of Standards and Technology. It seeks to contain information on all inorganic crystal structures published since 1913, including pure elements, minerals, metals, and intermetallic compounds (with atomic coordinates). ICSD contains 161,030 entries as of April 2013 and is updated twice a year.
A Windows-based PC version has been developed in co-operation with the National Institute of Standards and Technology (NIST), and a PHP-MySQL web based version in co-operation with the Institut Laue–Langevin (ILL) Grenoble.
