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

摘要

The zinc complex with neutral organochalcogen ligand Mbit, [(Mbit)2Zn](Cl O4)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, C18H24Cl2N8O8S4 Zn, Mr = 744.96, triclinic, space group P1, a = 11.2923(18), b = 11.9353(19), c = 13.837(3) , α = 114.763(2), β = 92.132(2), γ = 116.039(2)°, V = 1464.6(5) 3, Z = 2, Dc = 1.689 g/cm3, λ = 1.54184 , μ = 1.363 mm-1, F(000) = 760, S = 1.098, the final R = 0.0554 and w R = 0.0.1579. Complex 1 exhibits photocatalytic activity for methyl orange(MO) degradation under UV light and shows good stability toward photocatalysis.
