An organic-inorganic hybrid compound Na-2(HAn)(8)[H2W12O42]center dot 16H(2)O (HAn: p-anisidinium, C7H10NO) has been synthesized under soft acidic conditions and characterized by infrared and UV-visible spectroscopies, thermogravimetric analysis, cyclic voltammetry and single crystal X-ray diffraction. The compound crystallizes in the monoclinic P2(1)/n space group with a = 10.1920(4) , b = 34.2901(9) , c = 14.0745(5) , beta = 95.830(3)A degrees, V = 4,893.4(3) (3) and Z = 4. The compound exhibits a 2D supramolecular structure formed by alternated [paradodecatungstate/Na] and p-anisidinium layers. The catalytic activity of the compound for oxidation of cyclooctene with H2O2 was proved and gives rise to good reaction yield.
