通过三羰基(三甲硅环戊二烯基)钼负离子盐[η-M_e_3sic_5H_4Mo(CO)_3]_-Li_+氧化偶联合成了Mo-Mo键双核化合物(1),在甲苯中回流制得含Mo≡Mo 叁键化合物(2),乙炔对这Mo≡Mo键加成形成四面体形配合物(3),经元素分析.IR和_1HMR谱表征了标题化合物的结构.并用X射线衍射测定了配合物[η-M_e_3sic_5H_4Mo(CO)_3]_2(1)的晶体结构.1为单斜晶系,空间群为P2_1/c,晶体学数据:a=1.2826(2),b=0.8211(5),c=1.2902(1)nm,β=1.0480(2)°,V=1.3138nm_3,Z=2,D_ x= 1. 604g.cm_-_3,μ=10.530cm_-_1,F(000)=636.硅桥联双[三羰基(三甲硅基环戊二烯基)钼]负离子盐E[η-M_e_3sic_5H_4Mo(CO)_3]_2_2_-Li_+_2,[E=SiMe_2,...

The Mo-Mo bond dinuclear compounds were synthesized via oxidative coupling tricarbonyl trimethyl silylcyclopentadienyl molybdenum anion salt and silylene-bridged his (tricarbonyl trimethyl silylcyclopentadienyl molybdenum anion salt) E[eta-Me(3)SiC(5)H(3)Mo(CO)(3)]Li-2-(2)2(+), [E=SiMe(2), O(SiMe(2))(2)], respectively. Compound of containing molybdenum-molybdenum triple bond was also prepared by heating under reflux 1 in toluene. Acetylene add to the Mo = Mo triple bond to give tetrahedron complex, structures of the title compounds were characterized by elemental analyses, IR and H-1 NMR spect...
