摘    要:In the presence of NH4PF6, reaction of PPh4](η5-C5Me5)WS3Cu3Br(dppm)] with excess pyridine afforded red prismatic crystals, (η5-C5Me5)WS3Cu3Br(Py)3(dppm)](PF6) (1). It was characterized by elemental analy-sis, IR, UV-vis and 1H NMR spectroscopy and X-ray diffraction. 1 crystallizes in an orthorhombic system with space group Pna21 and unit cell parameters a=2.1124(4)nm, b=1.8944(4)nm, c=1.3338(2)nm, V=5.3375(19)nm3Z=4, Dc=1.807g·cm-3Mr=1452.42, F(000)=2864, μ=4.342mm-1R1=0.0487, wR2=0.1027. The structure of the cluster cation contains an incomplete cubane-like WS3Cu3 core where Cu(1) and Cu(2) atoms are bridged by a dppm ligand. Each of the three Cu atoms adopts a distorted tetrahedral coordi-nation geometry. The W-Cu(1), W-Cu(2) and W-Cu(3) distances are 0.27698(17)nm, 0.2772(17)nm, and 0.27065(9)nm, respectively.
