Abstract
Four new coordination complexes of palladium(II) and platinum(IV) starting from bis(dimethylthiocarbamoyl)sulphide (L1) and bis(diethylthiocarbamoyl)disulphide (L2) were synthesized and characterized in solid state by elemental analysis, infrared and electronic spectroscopy as well as thermal analysis (TG/DTA). The complexes were formulated on the basis of experimental data as [Pd(Me2NCS2)2] (1), [Pt(Me2NCS)2SCl4]·3H2O (2), [Pd(Et2NCS2)2] (3) and [Pt(Et2NCS)2S2Cl4]·4H2O (4), respectively. TG experiments revealed the nature of complex species as hydrated (2 and 4) or anhydrous (1 and 3). Thermal decomposition of coordinated organic ligands occurs in one or two exothermic stages, the final residue being in all cases the free metal (Pd or Pt).
