摘要：

The electrochemical redox behavior of Fe(II)/Fe(III)systems formed during the oxidation of complexes [Fe(C7H4NO3S)(2) (H2O)(4)] center dot 2H(2)O (Fe-sac) and [Fe(C7H4NO3S)(2) (C12H8N2] center dot 2H(2)O (Fe-sac-phen) have been investigated using cyclic voltammetry in the aqueous medium. In the CVs one pair of well-defined cathodic and anodic peaks appear for the transfer of single electron in the Fe-sac complex. The peak potentials are much wider separated as compared with the free (uncoordinated) Fe(II)/Fe(III) system. The. E values demonstrate that the electrode process is irreversible. In the presence of secondary ligand, 1,10-phenanthroline (Fe-sac-phen complex), the redox behavior of iron complexes is quasireversible. The effect of pH on the redox behavior of iron system is studied in acetate buffer.
