Mixed ligand complexes of Fe(II) with 2,2'-Bipyridyl (bipy) and some aromatic amines (L) (L = 3,4-diamino benzoic acid (DABA), 2-hydazinopyridine (hzpy) or 4-chloro-o-phenylenediamine (4-Cl-o-PDA) have been synthesized and characterized using IR, Mass, and UV-Vis spectrometry, magnetic susceptibility and thermal analysis. The complexes have been proved to have an octahedral geometry with equilibrium between high spin and low spin states which is reflected from the values of the mu(eff) (3.34-4.09). The electrochemical properties of these complexes have been studied using cyclic voltammetry. The structure of the Fe(II)-complexes have been geometrically optimized using parameterized PM3 semiempirical method. The photovoltaic performances of the complexes have been tested.
