摘要: 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 dppe molecules acting as both bridging and chelating ligands the thione coordinating monoanionic form through sulfur atom. environment around copper distorted tetrahedral. Crystal data: P21n, a =16.640(3), b=14.437(3), c=18.321(4) A, β=101.41(3)°, V=4312(1) A3, Z=2, Dcalc=1.299 g cm−3, R=0.0627 for 2723 reflections.
