ELECTROCHEMICAL SYNTHESIS OF ZINC AND CADMIUM COMPLEXES WITH 2-PYRROLYL)METHYLIDYNE]N'-TOSYLBENZENE-1,2-DIAMINE - THE CRYSTAL-STRUCTURE OF METHYLIDYNE]N'-TOSYLBENZENE-1,2-DIAMINATO)ZINC(II)

Electrochemical oxidation of zinc and cadmium in a solution of pyrroly l)methylidyne]-N'-tosylbenzene-1,2-diamine, H2L, in acetonitrile affor ded the compounds [M(HL)(2)], M=Zn, Cd. The crystal structure of bis-{ N-[(2-pyrrolyl ethylidyne]-N'-tosylbenzene-1,2-diaminato}zinc(II) has been determined by X-ray diffraction. The structure consists of monome ric molecules with the zinc atom in a distorted tetrahedral geometry. The IR and H-1 NMR spectra of the complexes are discussed and related to their structures.
