ICSD [Inorganic Crystal Structure Database] Web
Comprehensive database on fully determined inorganic crystal structures. It is produced by FIZ Karlsruhe and currently contains about 185,000 crystal structures. Updates are made twice a year (in spring and in fall) with data taken from scientific journals and other sources. About 6,000 structures are added to ICSD each year. Each set of data contains the complete structure information on an inorganic crystal compound.
Bibliographical information on the structure for further research is also provided. Physical and chemical properties are searchable.
