Abstract
A brief review of works on the crystal chemical features of the structure and methods of describing crystal structure types is presented. A variant of the universal system of a symbolic description of crystal structure types and modular structures with the use of structure codes is proposed. The structure code is based on a description of the geometry and topology of the basic structure module. Structure codes are intended for the identification and systematization of the structure types of compounds, the formalization of topological structural transformations, the determination of structural modules, and the derivation of genetic relationships between the structures.
