摘要:
The crystal structures of [Cd(tsac)(2)(im)(2)] (1) (tsac = anion of thiosaccharine; im = imidazole) and of (Him)[Cd(tsac)(3)(H2O)] (2) (Him = imidazolium cation) have been determined at 120 K by single crystal X-ray diffractometry. Complex 1 crystallises in the monoclinic space group P2(1)/a with Z = 4 whereas compound 2 is triclinic, space group P(- 1) and Z = 2. In both compounds, Cd(II) is in a distorted tetrahedral environment. In the neutral complex I the metal is coordinated to the Satom of the two thiosaccharinato ligands and to the N-atom of the imidazole molecules. In the anionic complex 2, Cd(II) is coordinated to three thiosaccharinato S-atoms and to the O-atom of the water molecule. The FTIR spectra of both compounds were also recorded and briefly discussed.
