Nomenclature of inorganic structure types. Report of the International Union of Crystallography Commission on Crystallographic Nomenclature Subcommittee on the Nomenclature of Inorganic Structure Types

Different degrees of similarity between inorganic crystal structures are defined concisely and examples are presented that illustrate their practical application. A notation giving the coordination of atoms is presented together with some basic rules for developing crystal-chemical formulae and the Bauverband description of inorganic structure types. Typical examples of the nomenclature are: pyrite Fe [6°] {g}[S 2 (3;1) t ], [ F (□2 l ) + F ′FeS 2 Pa\bar 3; spinel Mg [4] AI 2 [6] O 4 , ∞ 3 [Mg [4 t ] lAl 2 [6 o ] O 4 [l,3;12 co ] ], F m 222 + D , T ′ MgAI 2 O 4 Fd \bar 3 m .
