Cyclic voltammograms for the reduction of Pd<SUP>0</SUP> and Pt<SUP>0</SUP> complexes with mixed ligands of diimine and olefin exhibit, respectively, two or four reversible one-electron steps. The half-wave potentials of each step give a straight line with a slope of 1.0, when plotted against the half-wave potentials of diimine ligands, and a slope smaller than 0.2, when plotted aganist the half-wave potentials of olefinic ligands. The half-wave potentials of the complexes are affected only a little by the difference in the central metal. These findings lead to the conclusion that each LUMO of these complexes is dominated by the diimine π<SUP>*</SUP>-orbital, though it is higherlying than the olefinic π<SUP>*</SUP>-orbital in free ligands.
