Trans‐bis(saccharinato)cadmium(II) Complexes with 2‐Pyridylethanol: Synthesis,Crystal Structures,Spectral and Thermal Characterization of [Cd(sac)2(pyet)2] and [Cd(sac)2(H2O)(dmso)(pyet)]

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 (P2₁/c) and orthorhombic P2₁2₁2₁] 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.
