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)

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