摘　　要：The title compound [Cu(dtp) PPh3]2 (dtp=S2,P(OEt)2) was prepared by heating the mononuclear compound Cu(dtp)(PPh3)2 in CH3CN solution.It crystallizes in the triclinic space group P1 with parameters a=9.71 6(5),b=11.026(5),c=12.475(4) A.α=78.16(3)°,β=102. 64(4), γ=114.34(4)°,V=1178(1)A 3,Z=1,Dc=1.44 g/cm3,MoKα(λ=0.71069 A) μ=12. 48cm-1,F(000)=528.Final R=0.041.Rω= 0. 052 for 3653 unique intensity data(I≥3σ(I)).The molecule of the title compound can be viewed as a centrosymmetric dimer with two[Cu(dtp)(PPh3)] units,which are bridged by two S atoms belonging to the dtp ligands.The exact planar[Cu2S2] core and two[CuS2P] four-membered rings form a chair conformation.The Cu…Cu distance is 2.991(5) A.
