| Abstract: 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)nm3， Z=4， Dc=1.807g·cm-3，Mr=1452.42， F(000)=2864， μ=4.342mm-1， R1=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.
