Résumé / Abstract

A novel and highly efficient approach for the synthesis of H2Me2bqb and H2Me2bpb using ionic liquid as an environmentally benign reaction medium has been developed, eliminating the need for the pyridine as a toxic solvent. The Ni(II) complex of the dianionic ligand Me2bqb2-, [Me2bqb2- = = 1,2-bis(quinoline-2-carboxamide)-4,5-dimethyl-benzene dianion], has been synthesized and characterized by elemental analyses and spectroscopic methods, and the crystal and molecular structure of [Ni(Me2bqb)] (1), has been determined by X-ray crystallography. The complex exhibits distorted square-planar NiN4 coordination geometry with two short and two long Ni-N bonds (Ni-N ~1.85 and ~1.96 Å, respectively). The electrochemical behavior of [Ni(Me2bqb)] (1), has been studied by cyclic voltammetry and compared with the analogous complex, [Ni(Me2bpb)] (2).
