Abstract
Treatment of WS2Cl2 with pyridine (py) at room temperature leads to a redox reaction and the formation of a tungsten(V) species [W2S4Cl2(py)4]·2py (1) which contains the [(S)W(µ-S)2W(S)]2+ fragment and six-co-ordinate metal atoms. Crystals of (1) are monoclinic, space group P21/c, with a= 10.636(8), b= 23.180(15), c= 14.529(12)Å, β= 102.5(1)°, and Z= 4.1 245 Independent reflections above background were measured on a diffractometer and the structure refined to R 0.079. The [(S)W(µ-S)2W(S)]2+ fragment exists in the syn form with a W–W bond [2.844(4)Å] and two terminal W–S bonds [2.17(2), 2.13(2)Å].Keywords
