Synthesis, characterization, spectroscopy, electronic and redox properties of a new nickel dithiolene system.
A new dithiolene ligand with 3,5-dibromo substituted phenyl groups was designed and synthesized. The protected form of the ligand was reacted with a nickel salt providing neutral Ni(S(2)C(2)(3,5-C(6)H(3)Br(2))(2))(2) and anionic [Ni(S(2)C(2)(3,5-C(6)H(3)Br(2))(2))(2)](-) isolated as a Bu(4)N(+) salt. Both were characterized by UV-visible and IR spectroscopy and compared with the similar known molecular systems. They exhibit intense low-energy transitions that are characteristic of such systems. The electrochemical behavior of these molecules was investigated by cyclic voltammetry.
