Synthesis, Characterization And Crystal Structures Of Platinum(Ii) Saccharinate Complexes With 1,5-Cyclooctadiene, Ceyda İçsel

Turkish Journal of Chemistry

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 [PtCl$_{2}$(COD)] with Na(sac) • 2H$_{2}$O. The addition of the sac ligand resulted in the replacement of 1 and 2 chlorido ligands in [PtCl$_{2}$(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 $\pi $-donor ligand, …
