合成了含Mo(O)的三核化合物(Et_4N)_2.[(CO)_4Mo(μ-S)_2Mo(μ-S)_2Mo(CO)_4](Ⅰ)和(Et_4N)_2[(CO)_4Mo(μ-S)_2W(μ-S)_2Mo(CO)_4](Ⅱ),测定了(Ⅰ)的晶体结构.Ⅰ属单斜晶系,空间群P2_1/c,a=22.790(5),b=8.701(1),c=17.764(5)(?).γ=94.09(2)°,Z=4,最终R=0.045.Ⅰ的阴离子中,三个Mo间键角175°,接近共线.整个阴离子可以看作是由2个以Mo(0)为中心的八面体和1个以Mo(Ⅵ)为中心的准四面体分别共用一条边(各由2个μ-S原子连线所成)组成的结构.Mo-Mo-Mo键距分别是2.998(1)和3.000(1),Mo(μ-S)_2Mo共平面.
(Et_4N) _2 [(CO) _4Mo (μ-S) _2Mo (μ-S) _2Mo (CO) _4] (I) and (Et_4N) _2 [(CO) The crystal structure of (Ⅰ) was determined. The crystal belongs to the monoclinic space group P2_1 / c, a = 22.790 (5) γ = 94.09 (2) °, Z = 4, final R = 0.045. Among the anions of I, the bond angles of the three Mo are 175 °, which are close to The total anions can be regarded as the two octahedra centered by Mo (0) and the quasi-tetrahedron centered by Mo (VI) sharing one edge (each consisting of two μ-S atoms Line formed by the composition .Mo-Mo-Mo bond distance is 2.998 (1) and 3.000 (1) , Mo (μ-S) _2Mo coplanar.
