Additivity of the effect of ligand parameters on the redox potential of the Cu(II)/Cu(I) pair

The redox potential of Cu(II)/Cu(I) complexes with polydentate ligands can be calculated from the equation (V relative to the normal hydrogen electrode). In this paper, we give 13 E_i parameters, quantitatively reflecting various electronic and steric properties of the ligands.Slovak PoIytechnicaI Institute, Bratislava.
