STRUCTURAL SUBLATTICES, PSEUDOSYMMETRY IN COMPLEX CRYSTALLINE COMPOUNDS

Abstract

The paper reviews the methods of complex crystal structure symmetry description based on their representing with a set of Bravais sublattices. Due to the fact that sublattices in the structure are of higher symmetry than the crystalline sublattice, the composite crystal is of latent symmetry or pseudosymmetry, which reveals in its physical and physicochemical properties. The investigation methods of suchsymmetry are presented.
