Abstract

Four new mononuclear Pd(II) complexes of the type [PdX2(tdmPz)] {X = Cl (1); Br (2); I (3); SCN (4); tdmPz = 1-thiocarbamoyl-3,5-dimethylpyrazole} have been synthesized and characterized by elemental analysis, IR spectroscopy, 1H and 13C{1H}-NMR experiments. The thermal behavior of the complexes 14 has been investigated by means of thermogravimetry (TG) and differential thermal analysis (DTA). From the initial decomposition temperatures, the thermal stability of the complexes can be ordered in the sequence: 3 < 42 < 1. The final products of the thermal decompositions were characterized as metallic palladium by X-ray powder diffraction.
