μ-[1,2-Bis(diphenylphosphino)ethane]bis(3-trimethylsilyl;-pyridine-2- thiolate-S) [1,2-bis(diphenylphosphino)ethane]dicopper(I), [Cu2(3-Me3Sipyt)2(dppe)3], was obtained by reaction of [Cu(3-Me3Sipyt)] with 1,2-bis(diphenylphosphino)ethane (dppe) in acetone. The compound is dimeric with dppe molecules acting as both bridging and chelating ligands and the thione coordinating in the monoanionic form through the sulfur atom. The environment around the copper is distorted tetrahedral. Crystal data: P21/n, a=16.640(3), b=14.437(3), c=18.321(4) Å, β=101.41(3)°, V=4312(1) Å3, Z=2, Dcalc=1.299 g cm-3, R=0.0627 for 2723 reflections.
