中文摘要：
1,2-Diphenyl-1,2-dimethyldisilanylene-bridged bis-cyclopentadienyl 建筑群[5,5-C5H4PhMeSiSiMePh-C5H4 ] Fe2 (公司) 2 (-CO)2 (1 ) 被一个修改过程，以前是困难的获得的 trans 异构体 1b 第一次从被孤立综合。更有趣地，二新regio异构体[ 5,5-C5H4SiMe ( SiMePh2 ) C5H4 ] Fe2 (公司) 2 ( -CO)2 ( 2 )并且[ 5,5-C5H4Me2SiSiPh2C5H4 ] Fe2 (公司) 2 ( -CO)2 ( 3 )偶尔在上面期间被获得过程，哪个为这类 SiSi 包含契约的转变金属建筑群的进一步的学习开创了新选择的新奇结构。2 的分子的结构被 X 光检查衍射方法决定了。
英文摘要：
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.
