Structure of “Coordination Oligomers” Based on Complexes of Thiophosphorylthiourea Compounds With Monovalent Copper and Silver Cations

Molecular and crystal structures of two polynuclear complexes of monovalent silver and copper with chelate thiophosphorylthiocarbamide ligands is determined within the study of complexing properties of N-thiophosphorylated thioureas with respect to copper(I) and silver(I) cations. In crystals, these complexes are shown to form “coordination oligomers” (closed polynuclear complexes) through coordination bonds of bridging sulfur atoms of thiocarbamide groups.
