摘要
1,2-Diphenyl-1,2-dimethyldisilanylene-bridged bis-cyclopentadienyl complex [η^5,η^5-C5H4PhMeSiSiMePh-C5H4]Fe2（CO）2μ-CO）2 （1） was synthesized by a modified procedure, from which the trans-isomer lb that was previously difficult to obtain has been isolated for the first time. More interestingly, two new regio-isomers [η^5,η^5- C5H4SiMe（SiMePh2）C5H4]Fe2（CO）2（μ-CO）2 （2） and [η^5,η^5-C5H4Me2SiSiPh2C5H4]Fe2（CO）2（μ-CO）2 （3） were occasionally obtained during above process, the novel structures of which opened up new options for further study of this type of Si-Si bond-containing transition metal complexes, The molecular structure of 2 has been determined by the X-ray diffraction method.
