Abstract: A new unsymmetrical tetradentated Ni(Ⅱ) Schiff base complex of 3-{1-[2-(3-hydroxy-1-methyl-but-2-ebylideneamino)-pheno-ylimino]-ethyl}-4-methylthio-penta-2,4-dien-2-ol (2) was synthesized in one pot via the reaction of nickel(Ⅱ) acetate, o-phenylene diamine, and 5-(2-acetyl-1-methylthio-3-oxo-butylidene)-2,2-dimethyl-dioxane-4,6-dione (1). Compound 2 was characterized by elemental analysis, IR, 1H NMR spectra, X-ray diffraction patterns and cyclic voltammogram method. The crystal of complex 2 belongs to monoclinic space group: P21/C, with a=1.147 6(2) nm, b= 1.178 2(2) nm, c=1.481 0(3) nm, β=111.73(2)°, V=1.860 2(7) nm3, Z=4, Rf=0.053 5.
