Zinc Complexes Based on Organochalcogen Ligand Mbit: Syntheses, Structures and Photocatalytic Properties

The zinc complex with neutral organochalcogen ligand Mbit, [(Mbit)(2)Zn](ClO4)(2) (1, Mbit = 1,1'-methylenebis(3-methyl-imidazole-2-thione)), has been synthesized and characterized. The complex has been characterized by elemental analysis, NMR and IR spectra. The molecular structure of 1 has been determined by X-ray crystallography. For the complex, C18H24Cl2N8O8S4Zn, M-r = 744.96, triclinic, space group P (1) over bar, a = 11.2923(18), b = 11.9353(19), c = 13.837(3) angstrom, alpha = 114.763(2), beta = 92.132(2), gamma = 116.039(2)degrees, V = 1464.6(5) angstrom(3), Z = 2, D-c= 1.689 g/cm(3), lambda = 1.54184 angstrom, mu = 1.363 mm(-1), F(000) = 760, S = 1.098, the final R = 0.0554 and wR = 0.0.1579. Complex 1 exhibits photocatalytic activity for methyl orange (MO) degradation under UV light and shows good stability toward photocatalysis.
