This communication will describe the electron doping effect into Ni III complexes by CuII ions, [Ni1-xCu x(chxn)2Br]Br2-x (x = 0.038 and 0.101) by using an electrochemical oxidation method. A drastic increase of electrical conductivity as well as a new absorption band around 0.5 eV in single crystal reflectance spectra was observed by doping CuII ions, indicating the electron doping was successfully made. An ESR result shows unpaired electrons locate in the dx2-y2 orbitals of CuII and have almost no interaction with those of other ions.
