Synthesis, solution and spectral studies of palladium(II) complexes with 2-hydroxyacetophenone N(3)-propylthiosemicarbazone. Crystal structure of a tripalladium complex

The reactions of palladium(II) salts with 2-hydroxyacetophenone N(3)-propylthiosemicarbazone, H2Ap3Pr, are described. The synthesis and spectral characterization of a new triangular, trinuclear palladium(II) complex with the dianion, Ap3Pr2−, are reported. The X-ray crystal structure determination of [Pd(Ap3Pr2)]3·DMF shows it to contain a chair-form hexagon of alternating Pd and S atoms to form a molecular bowl. The spectrophotometric characterization of H2Ap3Pr is also reported.
