The reaction of 6-methyl-2-acetylpyridine 3-hexamethyleneiminylthiosemicarbazone, H6MAchexim, with potassium tetrachloro-palladate(II) and tetrachloroplantinate(II) in methanol afforded the complexes [Pd(6MAchexim)Cl] and [Pt(6MAchexim)Cl], respectively. The X-ray crystal structure determination of both shows that anions of H6MAchexim coordinate in a planar conformation to the central palladium(II) or platinum(II) via the pyridyl nitrogen, azomethine nitrogen and thiolato sulfur atoms. The complexes have also been characterized by spectroscopic techniques (IR, UV-VIS and H-1 NMR). (C) 1999 Elsevier Science Ltd. All rights reserved.
