Two new platinum(II) complexes, namely [PtCl(sac)(COD)] (1) and [Pt(sac)(2) (COD)] (2) (sac = saccharinate and COD = 1,5-cyclooctadiene), were synthesized and characterized by elemental analysis, IR, NMR, ESI-MS spectroscopic and thermal analysis (TG/DTA) methods. The platinum(II) complexes were prepared from the reaction of [PtCl2 (COD)] with Na(sac)center dot 2H(2)O. The addition of the sac ligand resulted in the replacement of 1 and 2 chlorido ligands in [PtCl2 (COD)] to yield 1 and 2, respectively. The structures of the complexes were determined by single crystal X-ray diffraction and showed a distorted square planar coordination geometry around platinum(II). COD acted as a p-donor ligand, while sac was N-coordinated in both complexes. The TG/DTA data indicated that both complexes were thermally stable up to 220 degrees C in air and their thermal decompositions yielded Pt as a final product. Complexes 1 and 2 were also designed as possible precursors to synthesize new mixed-ligand platinum(II) sac complexes in a one-pot reaction.
