  Synthesis, structure and electrochemistry of Co(III) complexes with an unsymmetrical Schiff base ligand derived from 2-aminobenzylamine and pyrrole-2-carboxaldehyde

  摘要：

  A series of cobalt(III) complexes with a new unsymmetrical tetradentate Schiff base ligand N,N'-bis(pyrrol-2-ylmethylene)-2-aminobenzylamine. H(2)pyrabza, formed by the condensation of 2-pyrrole carboxaldehyde and 2-aminobenzylamine, has been synthesized and characterized by elemental analyses, IR, UV-Vis and H-1 NMR spectroscopy. These complexes have the general formula trans-[Co-III(L)(amine)(2)]X {L2- = pyrabza, and amine = N-methylimidazole (N-Melm) (1), 3-methylpyridine (3-Mepy) (2), 4-methylpyridine (4-Mepy) (3), pyridine (py) (4), X = BPh4-}. The structure of compound 1 has been determined by X-ray crystallography. The geometry around the central cobalt ion is distorted octahedral. The electrochemical behavior of these complexes was also investigated. The reduction potential of Co(III), ranging from -0.79 V for 1 to -0.44 V for 4, shows a relatively good correlation with the sigma-donor ability of the axial ligands. (C) 2011 Elsevier Ltd.
