| Abstract: The trionuclear complexes of (Et4N)2[(CO)4Mo(μ-S)2M(μ-S)2Mo(CO)4](Ⅰ) and(Et4N)2[(CO)4Mo(μ-S)2M(μ-S)2Mo(CO)4](Ⅱ) were synthesised,and molecule structure of (Ⅰ) was determined by X-ray diffraction.Complex (Ⅰ) belongs to monoclinic system and the space group is P21/c,with a=22.790(5)Å,b=8.701(1)Å,c= 17.764(5)Å.γ= 94.09(2)°,Z=4,R=0.045.In the anion of (Ⅰ),the bond angle of Mo(0) Mo(Ⅵ)Mo(0) is 175 °and the 3Mo atoms lie approximately in a line.The anion of (Ⅰ) can be regarded as the structure composed of two octahedrons with two Mo(0) atoms in the center respectively and one near-tetrahedron with the Mo(Ⅵ) atom in the center sharing two edges which are the line between the bridged sulfur atoms respectively.The Mo-Mo-Mo distances,being 2.998(1)Å and 3.000(1)Å,and the bimetallic center Mo(μ-S)2Mo is planar. |
