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.
