Anions [loss of N(3) hydrogen of 2-acetylpyridine N(4)-dimethylthiosemicarbazone (HAc4DM)] coordinate in a planar conformation to a central palladium(II) through the pyridyl nitrogen, azomethine nitrogen and thiolato sulfur atoms. The fourth coordination site is occupied by either a bromo, chloro or a second Ac4DM ligand bonding via its thiolato sulfur atom. A crystal structure of [Pd(Ac4DM)Br] shows it to be planar, while the structure of [Pd(Ac4DM)(2)] has the unusual coordination of the two anions bonding differently to the palladium centre. Spectral and structural similarities and differences between these and related nickel(II) and copper(II) complexes are considered. Copyright (C) 1996 Elsevier Science Ltd (EN)
