| Abstract: | A supramolecular compound, Cu2(HL)7(H2O)2(SiW12O40)3]·(H2L)0.5·20.5H2O, based on Keggin-type polyoxometalate anions and metal-organic cations and non-linear 1,3,4-oxadiazole derivatives was obtained via hydrothermal reactions. We structurally characterized the compound using infrared spectroscopy, thermogravimetric analysis and single-crystal X-ray diffraction. The electrochemical properties of a bulk modified carbon-paste electrode based on the supramolecular compound were studied in 1 mol/L H2SO4 aqueous solution. The results indicate that the compound is a monoclinic system with a C2/c space group. The basic building blocks of the compound are Keggin-type SiW12O404-anions; metal-organic units, Cu2(HL)7(H2O)2]11+; a discrete protonated ligand, 2-(3-pyridyl)-5-(4-pyridyl)-1,3,4-oxadiazole; and water molecules. The supramolecular compound has a high level of electrocatalytic activity. |
