摘要：

The thiohalide complex of tungsten (Et4N)2W2S4Br4 interacts with PPh3 to produce the W2S4Br2(PPh3)2·C6H6 complex (I). The crystals of I are triclinic, space group P1 (a = 10.573(2), b = 14.054(3), c = 16.751(4) Å, α = 111.10(2), β = 90.24(1), γ = 110.01(1)°, Z = 2). A total of 1623 independent observed reflections have been obtained on an automated diffractometer and the structure was refined to R = 0.0734. Complex I has a syn-[(S)W(μ2S)2W(S)]2+ fragment. The bromine atoms are in a trans position. The WW distance is 2.813(3) Å and the WSt distance is 2.10(1) and 2.115(9) Å. © 1990.
