Abstract

This communication will describe the electron doping effect into Ni ^III complexes by Cu^II ions, [Ni_1-xCu _x(chxn)₂Br]Br_2-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 Cu^II ions, indicating the electron doping was successfully made. An ESR result shows unpaired electrons locate in the d_x2-y2 orbitals of Cu^II and have almost no interaction with those of other ions.
