Trinuclear palladium(II) complexes with 2-hydroxy-4-methoxyacetophenone N-4-dimethylthiosemicarbazone: Synthesis, spectral studies and crystal structure of a tripalladium complex

The synthesis and spectral characterization of a new triangular, trinuclear palladium(II) complex with the dianion of 2-hydroxy-4-methoxyacetophenone N-4-dimethylthiosemicarbazone, 4MeOAp4Me(2)(2-) is reported. The X-ray crys tal structure determination of [Pd(4MeOAp4Me(2))](3). DMSO shows it to cont ain a chair-type hexagon of alternating Pd and S atoms which form a molecul ar bowl. The crystal structure of H(2)4MeOAp4Me(2) shows that it is the E i somer with respect to the imine bond of the thiosemicarbazone moiety.
