| Abstract: | The reaction of (NH4)2Mo2S12]?H2O with excess CuBr in pyridine gave rise to a new hexanuclear cluster MoS4Cu5Br3(Py)7] 1 which crystallizes in the triclinic system, space group P with a = 11.6274(4), b = 12.0127(4), c = 18.8872(5) , a = 82.46(2), b = 73.25(2), g = 62.800(13) , V = 2246.8(2) ?, Z = 2, Mr = 1335.37, F(000) = 1300.0, Dc = 1.974 g/cm3, m = 5.482 mm1, R = 0.042 and Rw = 0.048. The molecular structure of 1 is composed of two nido-like MoS3Cu3] cluster units which are interconnected by sharing the same MoSCuS plane, forming a twin nido-like MoS4Cu5] cluster framework. The Mo…Cu distances vary in the range of 2.6830(11)~2.741(2) ? |
