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 ]
The Crystallography Open Database (COD) is a database of crystal structures. [1] Unlike similar crystallographic databases , the database is entirely open-access, with registered users able to contribute published and unpublished structures of small molecules and small to medium-sized unit cell crystals to the database.
The translations form a normal abelian subgroup of rank 3, called the Bravais lattice (so named after French physicist Auguste Bravais). There are 14 possible types of Bravais lattice. The quotient of the space group by the Bravais lattice is a finite group which is one of the 32 possible point groups.

The law of symmetry is a law in the field of crystallography concerning crystal structure. The law states that all crystals of the same substance possess the same elements of symmetry. The law is also named the law of constancy of symmetry, Haüy's law or the third law of crystallography.
