Abstract
Topological analysis and crystal-chemical classification of 67 compounds with tetrahedral anions with the general formula My(TQ4)z (T = Si, Ge, P, As; Q = S, Se, Te) have been carried out. These compounds are classified into 36 topological and 38 structure types. Cases of similarity of ternary anhydrous salts My(TQ4)z to binary compounds AyXz are revealed and discussed with the use of the TOPOS structural topological program package. Analysis of the topology and uniformity of ionic matrices shows that the matrices of chalcogenide ions and tetrahedral TQ y−4 anions play, as a rule, a leading structural role in My(TQ4)z compounds.
