摘要： 合成了稀土铁双核配合物:(C5H5Fe(CO)2)LnCl2·nTHF(Ln=Nd,Sm,Gd;n=1,2)和(C5H5Fe(CO)2)(C5H4(SiMe3))·LnCl·nTHF(Ln=Nd,Sm,Gd;n=0,1,2)。元素分析,热分析,红外光谱和质谱分析确认了这两种配合物。红外光谱数据表明铁与稀土原子是以羰基桥连接。晶体结构分析表明((C5H5Fe(CO)2)Na·4THF是(C5H5Fe(CO)2)LnCl2·nTHF合成的中间体。

Abstract: In this paper the preparation of the binuclear complexes [C5H5Fe(CO)2]LnCl2·nTHF(Ln = Nd, Sm, Gd; n = 1,2) and [C5H5Fe(CO)2][C5H4 (SiMe3)]LnCl·nTHF (Ln = Nd, Sm,Gd; n = 0,1,3) is reported. Both complexes were identified by clemental analyses, thermalgravimetric analyses, infrared spectra, mass spectra, NMR and EPR. The infraredspectral data reveal the bridging carbonyls between the iron and the rare earth elements.[C5H5Fe(CO)2]2Na·4THF as a reaction intermediate in the preparation of [C5H5Fe-(CO)2]LnCl2 nTHF was characterized by crystal structural analyses.
