Synthesis, characterization and electrochemical properties of cyanide-bridged cobalt(III) iron(II) complexes

Five new cyanide-bridged cobalt(III)/iron(II) complexes have been synthesized. The complexes were characterized by elemental analyses, spectral analyses and electrochemical techniques. The presence of cyanide bridges is evident from the IR and UV-vis spectra by the shift of nu((C=N)) and changes in lambda(max) with respect to the mononuclear parent complex Fe(phen)(2)(CN)(2) (phen is I,10-phenanthroline). The cyclic voltammogram of cyano-bridged cobalt(III)/iron(II) complexes indicates that they all exhibit two pairs of reversible peaks.
