Spectrophotometric Studies of Cyano-Bridged Complexes of the Type [(Dien) M(II)-μ-NC-Fe(III)(CN)5]−

Abstract

Abstract Three kinds of new M(II)-μ-NC-iron(III) cyano—bridged complexes [(dien) M-NC-Fe(CN)5]− (M = Ni, Co, Cu) have been synthesized and characterized by elemental analysis, IR, UV—vis spectral analysis. The formation of cyano—bridges is evident from the IR and UV—vis spectra by appearance of v (C≡N) shifts and changes in λmax with respect to the mononuclear parent complex [Fe(CN)6]3−.
