摘要: 通过SnCl2对化合物Me2Si[η5-C5H4Fe(CO)]2(μ-CO)2(Ⅰ)中Fe-Fe键的插入反应以及Ⅰ被Na-Hg齐还原所生成的相应双铁负离子Me2Si[η5-C5H4Fe(CO)2]22-与SnR2Cl2(R=Me,Ph)的亲核反应,合成了环状化合物Me2Si[η5-C5H4Fe(CO)2]2SnR2[R=Cl(1),Me(2),Ph(3)].以元素分析、IR和1HNMR谱表征了它们的结构,并用X射线衍射测定了配合物3的晶体结构。3为单斜晶系,空间群P21/n,a=1.0384(3)nm,b=1.6384(1)nm,c=1.5762(5)nm,β=97.93(2)°,V=2.656(2)nm3,Z=4,Dx=1.71g/mL.

Abstract: The cyclic compounds of Me2Si[η5-C5H4Fe(CO)2]2SnR2[R=Cl(1),Me(2),Ph(3)] were synthesized via insertion of SnCl2 to Fe-Fe bond of complex 1,Me2Si[η5-C5H4Fe(CO)]2(μ-CO)2 and the reactions of the related dianion {Me2Si[η5-C5H4Fe(CO)2]2}2-with R2SnCl2(R=Me,PH).They were characterized by IR,1H NMR and elementary analysis. No expected product was isolated from the corresponding reactions of complex 2,(η55C5H4SiMe2OSiMe2H4)[Fe (CO)]2(μ-CO)2.The crystal structure of 3 was determined by X-ray diffraction. The crystals of 3 are monoclinic,space group P21/n with a=1. 0384(3)nm,b=1.6384(1) nm,c=1.5762(5) nm and β=97.93(2)°,V=2.656(2) nm3,Z=4,Dx=1.71g/mL.The final agreement factor,R=0.036.
