Crystallographic Information File (CIF) is a standard text file format for representing crystallographic information, promulgated by the International Union of Crystallography (IUCr). CIF was developed by the IUCr Working Party on Crystallographic Information in an effort sponsored by the IUCr Commission on Crystallographic Data and the IUCr ...
The CIF format is the standard file format for the exchange and archiving of crystallographic data. [1] It was adopted by the International Union of Crystallography , who also provides full specifications of the format. [2] It is supported by all major crystallographic databases.
The primary file format for CSD structure deposition, adopted around 1991, is the "Crystallographic Information file" format, CIF. [16] The deposited CSD files can be downloaded in the CIF format. The validated and curated CSD files can be exported in a wide range of formats, including CIF, MOL, Mol2, PDB, SHELX and XMol, using tools in the CSD ...

Crystallography is the branch of science devoted to the study of molecular and crystalline structure and properties. [1] The word crystallography is derived from the Ancient Greek word κρύσταλλος ( krústallos ; "clear ice, rock-crystal"), and γράφειν ( gráphein ; "to write"). [ 2 ]
In crystallography, space groups are also called the crystallographic or Fedorov groups, and represent a description of the symmetry of the crystal. A definitive source regarding 3-dimensional space groups is the International Tables for Crystallography Hahn (2002) .

In Hermann–Mauguin notation, space groups are named by a symbol combining the point group identifier with the uppercase letters describing the lattice type.Translations within the lattice in the form of screw axes and glide planes are also noted, giving a complete crystallographic space group.
