| Abstract: | Reaction of Mo(CO)6 with p-CH3-C6H4SNa and Et4NCl· H2O in CH3 CN afforded a dinuclear molybdenum (0) compound Et4 N ] 2 Mo2 (CO) 8 ( SC6 H4 -CH3-p)2 ] (1). The crystal structure of 1. 2 MeCN was determined by X-ray diffraction. The crystallographic data: C42H60Mo2N4O8S2, Mr = 1005.07, triclinic, P 1,a=9.694(3), b=9.999(3), c=13.012(2)(A。), a=99.72(2), β=97.01(1), γ=97.36(3)°, V=1219.5(1)(A。)3, Z=1, Dc=1.40g/cm3, F(000)=532, μ=6.3cm-1 , Final R =0.038 and Rw =0.046 for 4097 reflections with I＞3.0σ(I). The Xray structure analysis revealed that the Mo2 S2 core is planar. The geometry around each Mo atom is a distorted octahedron, both of which form an edge-sharing bioctahedron.The Mo…Mo distance is 4.0342(5)(A。),which obviously indicates the absence of Mo-Mo bond. |
