A database of structures and properties for various materials including polymers and inorganic substances. This database is maintained by National Institute of Materials Science (NIMS), and provides crystal structures, various physical properties, and phase diagrams for material science via a user interface based on web browsers. This database also provides calculation results of phase diagrams and electronic structures. This database can be used without charge after registration.
An open-access database of crystal structures. This database includes structural data of organic, inorganic, metal-organic compounds and minerals. At the end of 2017, this database contains about 400,000 entries. Three-dimensional structures of crystals can be viewed by GUI on the web.
