On the basis of the literature data and the results of our studies for the heterophase structure, domain structure, phase boundary and Raman scattering the phase diagram common for Cs2HgCl4, Cs2HgBr4 and Cs2CdBr4 is constructed.

Key words: optical indicatrix, incommensurate structure, domain structure, heterophase structure, phase diagram.
