Abstract

Two trans saccharinate (sac) complexes of cadmium(II) with 2-pyridylethanol (pyet) were synthesized and characterized by elemental analyses, FT-IR spectroscopy, thermal analysis and single crystal X-ray diffractometry. The [Cd(sac)(2)(pyet)(2)] (1) and [Cd(sac)(2)(H2O)(dmso)(pyet)] (2) complexes crystallize in the monoclinic (P2(1)/c) and orthorhombic [P2(1)2(1)2(1)] crystal systems, respectively. The sac ligands in both complexes are N-coordinated and located in trans positions, while the pyet molecules act as a bidentate N- and O-donor ligand forming two six-membered chelate rings. Thermal decomposition of the complexes in air results in elimination of aqua, dmso and pyet ligands, respectively, forming cadmium saccharinate as a stable intermediate, which also decomposes at higher temperatures to give cadmium oxide.
