catena-Poly[copper(I)-bis(μ-trifluoromethanesulfonato-κ2O:O′)-copper(I)-bis(μ-trimethyl trithiophosphite)-κ2P:S;κ2S:P]

The title compound, [Cu2(CF3SO3)2(C3H9PS3)2]n, crystallizes as infinite chains in which two trimethyl trithiophosphite ligands and two trifluoromethanesulfonate anions bridge the essentially tetrahedrally coordinated CuI ions in an alternating fashion. The P and one S atom of each trimethyl trithiophosphite ligand are employed for coordination. The molecular structure exhibits the rare motif of copper(I) bridged by two trifluoromethanesulfonate anions generating eight-membered rings
