通过三羰基(五甲二硅基)环戊二烯基钼负离子盐[η-Me_5Si_2C_5H_4Mo(CO)_3]_-Li_+的反应合成了标题化合物, 以元素分析、IR和1_H NMR谱表征了它们的结构, 并用X射线衍射测定了配合物[η-Me_5Si_2C_5H_4MoBr(CO)_3]和[η-Me_5Si_2C_5H_4Mo(CO)_3]_2的晶体结构。

The title compounds were synthesized via some reactions of tricarbonyl pentamethyldisilanylcyclopentadienyl molybdenum anion galt. Their structures were characterized by elemental analyses, IR and H-1 NMR spectra. Furthermore, the crystal structures of complexes eta-Me5Si2C5H4Mo(CO)3Br, (3) and [eta-Me5Si2C5H4Mo(CO)3]2, (4) were determined by X-ray diffraction. The crystals of 3 are orthorhombic, space group P(bca), with a = 1.3378(6), b = 1.5884(5), c = 1.7471(6) nm, V = 3.71 nm3, Z = 8, D(x) = 1.63 g.cm-3, mu = 24.3 cm-1, F(000) = 1808. The crystals of 4 are triclinic, space group P1BAR, wit...
