Intermolecular compound (Hdmpy)₁₁H(H₂W₁₂O₄₀)₂·6H₂O was prepared by the reaction of sodium tungstate dihydrate with 2,6-dimethyl pyridine(dmpy) and characterized by IR, UV spectroscopy and single crystal X-ray diffraction. The crystal parameters of the compound are as follows: monoclinic, P2₁/c space group, a=2.162 8(4), b=2.156 8(4), c=2.918 3(6) nm, β=92.92(3)°, V=13.596(5) nm³, Z=4, D_c=3.418 Mg/m³, R=0.056 5, wR=0.100 8. The crystal structure analysis reveals that the electrostatic and intermolecular interactions between protonated 2,6-dimethyl pyridine molecules and the polyanions form an infinite two dimensional network by means of W-O-H-N or W-O-H-C. Cyclic voltammetric curves of the polyoxoanion of the title compound in a 0.5 mol/L NaCl-HCl solution reveals the two-step one-electron reduction process.
