Synthesis and properties of cyano-bridged complexes [LmCo(III)-mu-NC-Fe-II(CN)(5)](-)

Four kinds of new cyano - bridge complexes have been prepared and characterized by elemental analysis, IR spectra, UV - Vis spectra, Luminescent spectra and electrochemical techniques. The formation of cyanide bridge is evident from the IR and UV - Vis spectra by appearance of (nu(C=N)) shifts and changes in lambda(max) with respect to the mononuclear parent complex [Fe(CN)](4-) and [CoLm](3+), respectively. The complexes studied are interesting as models for the design of energy conversion schemes.
