Abstract:

A single crystal complex [Ni(qina)2(H2O)2]·2DMSO(Hqina=quinaldinic acid, DMSO=dimethyl sulfoxide) was synthesized at room temperature by the solvent substitution method, which belongs to monoclinic system with space group C2/m. Two qina ligands chelate a nickel(Ⅱ) ion by O and N atoms and two H2O coordinate a Ni(Ⅱ) ion by two O atoms at an axis. The complex formed inerratic octahedron configuration, and H bonds, π-π stacking were observed between the molecules. 1-Naphthyl acetate hydrolysis velocity has been remarkably enhanced by the title complex, when the concentration of the title complex was at 1.0×10-4 mol/L, pH 8.44. The enhancement multiple was 365.
