Electrochemical synthesis of metal (II) complexes of Schiff base 2-tosylamino (2 '-pyridyl)aniline: the crystal structure of bis-[2-tosylamino(2 '-pyridyl)anilinato]cobalt(II)

摘要

Complexes of cobalt(II): nickel(II), copper(II), zinc(II) and cadmium(II) with the anion of the Schiff base 2-tosylamino (2'-pyridyl) aniline (HL) have been prepared by using an electrochemical procedure. These compounds were characterized by elemental analysis, IR, UV and NMR spectroscopy, and in the case of [CoL2] by X-ray diffraction methods. In this compound the cobalt(II) atom is in a distorted tetrahedral environment, each Schiff base anion acting as a bidentate ligand with the pyridine nitrogen atom uncoordinated.
