ready Crystallographic Information Framework


General Information
The acronym CIF is used both for the Crystallographic Information File, the data exchange standard file format of Hall, Allen & Brown (1991) (see Documentation), and for the Crystallographic Information Framework, a broader system of exchange protocols based on data dictionaries and relational rules expressible in different machine-readable manifestations, including, but not restricted to, Crystallographic Information File and XML.

Implementing Databases (2)
Crystallography Open Database
Crystal structures of small molecules. Open-access collection of crystal structures of organic, inorganic, metal-organic compounds and minerals, excluding biopolymers.

The Cambridge Structural Database
Established in 1965, the CSD is the world’s repository for small-molecule organic and metal-organic crystal structures. Containing over 800,000 entries from x-ray and neutron diffraction analyses, this unique database of accurate 3D structures has become an essential resource to scientists around the world.
