Octahedrally co-ordinated zinc and cadmium compounds with five-membered heterocyclic OS3N2 ligands

Abstract

The compounds [M(OS₃N₂)₆][AsF₆]₂(M = Zn or Cd) have been prepared in which the metal atoms are co-ordinated by six five-membered heterocyclic ligands. The molecular and crystal structures were determined by X-ray analysis. The metal is bonded to each ligand via the exocyclic oxygen atom, giving a slightly distorted octahedral environment. The S₃N₂ rings have an envelope conformation where the S atom connected to the oxygen is out of the plane formed by the other four atoms. The AsF₆^– group is slightly disordered in the cadmium compound, considerably disordered in the zinc compound.
