摘要

Heteroleptic nickel(II) complexes [NiL2L'] of a series of monoanionic and potentially bidentate' N-2-pyridyl-sulfonamide ligands [HL] and 2,2'-bipyridine or 1,10-phenanthroline (U) have been prepared by electrochemical oxidation of a nickel anode in an acetonitrile solution of the ligands. The complexes have been characterized by microanalysis, IR and electronic spectroscopy, magnetic measurements and LSI mass spectrometry. The crystal structure of [Ni(Ms6mepy)(2)(bipy)] has been determined by x-ray diffraction and shows the metal in an octahedral NiN6 environment. Octahedral structures are also proposed for the other complexes with the N-2-pyridyl-sulfonamide ligands acting as N,N' or NO bidentate systems, depending on the position of the methyl substituent on the pyridine ring.
