Abstract: 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 Cu^I 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.
