SYNTHESIS AND CHARACTERIZATION OF DICATIONIC NICKEL COMPLEXES

Abstract
Dicationic nickel complexes have been prepared by chemical and electrochemical oxidation of metallic nickel, by methathetical exchange of nickel chloride with halide abstracting agents (ZnCl2, Zn, AlCl3, Al) and by reaction of nickel acetate with strong Brönsted acids (HBF4, CF3SO3H). The resulting complexes were characterized by IR, UV-vis, Rutherford Backscattering Spectroscopy (RBS). and magnetic moment measurements as being octahedral, with six nitrile ligands.
