Synthesis and Structural Characterization of a Hetcrobimctallic Molybdenum-Copper-Sulfur Compound Et4N2 CMoCu3S4 （S2CNEt2）3

摘要

＜正＞ The title compound crystallizes in orthogonal space group P212121with α= 12. 848 （5）, b =13. 227 （3）, c = 29. 519（8） A ,Z = 4 , V= 5016. 5 A3 and Dc = 1. 483g/cm3. 4940 independent reflcctiions were collected on a CAD4 diffractometer with MoKa radiation in the range of 1°＜0＜25°,of which 3559 reflections having intensities I ＞3σ（I） were used for structure determination. The structure was solved by direct methods and refined by the least-squares method to final discrepancy factors R=0. 071 and Rw - 0. 075. The anion of the title compound can be described as a slightly distorted MoS42-tetrahedron coordinated by three [CuS2CNEt2] units ,with the four metal atoms lying approximately in a plane.
