X-RAY STRUCTURAL STUDY OF HALOGENCHALCOGENITE GOLD(III) COMPLEXES

X-ray structural study of the compounds AuX3(YZ4) where Y is S, Se or Te; X and Z are Cl or Br, has been carried out. Unit cell parameters, atom positions, interatomic distances and valence angles for four compounds are given in the paper. It have been shown that the gold atom in the molecule is surrounded by four halogen atoms which are situated in the vertices of a slightly distorted square. Chalcogen atom is in the vertex of a trigonal pyramid, base of which is formed by halogen atoms. Non-valent contacts of Y and X atoms have been observed. It has been shown that complexes containing Cl and Br, S and Se have similar crystal structure; introduction of Te, however, leads the change of the structural type.
