A series of copper(II) and copper(I) complexes, [CuX2L] (16) and [CuL2](CuX2) (7-12) (X = Cl, Br; L = 2-R-9-R′-l, 10phenanthroline, dpp: R = R′ = Ph; npp: R = naphthyl, R′ = Ph; dnp: R = R′ = naphthyl) were synthesized and characterized by elemental analysis, UV/Vis and IR spectroscopy, and Xray crystal diffraction (for 1, 3, 6, and 12), The copper(II) complexes are four-coordinate with one phenanthroline ligand and two halogen atoms, whereas the copper(I) complexes are tetrahedrally coordinated by two bidentate phenanthroline ligands. Cyclic voltammetry studies of the CuI complexes in CH2Cl2 reveal that bulky groups in the 2,9-positions have significant effects on the redox potential of the CuII/I couple, which is more positive for the complexes with the dnp ligand than those with the dpp and npp ligands,
