The reaction of warm EtOH solutions of FeX3.nH2O (X=Cl, NO3) with tridentate ONX (X=O, S, N) pyridoxal semi-, thiosemi- and S-methylisothiosemicabazones (H2L1, H2L2, H2L3, respectively) yielded high-spin octahedral mono- and bis(ligand) complexes of the formula [Fe(H2L1-3)Cl2(H2O)]Cl,[Fe(HL1,2)2]Cl.nH2O and [Fe(H2L3)(HL3)]NO3)2.H2O. The compounds were characterized by elemental analysis, conductometric and magnetochemical measurements, IR and UV-Vis spectra. Besides, a detailed voltammetric study of the complexes was carried out in DMF solution in the presence of several supporting electrolytes, to characterize the nature of the electrode processes and solution equilibria.
