Abstract

An organic–inorganic hybrid compound Na2(HAn)8[H2W12O42]·16H2O (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 P21/n space group with a = 10.1920(4) A, b = 34.2901(9) A, c = 14.0745(5) A, β = 95.830(3)°, V = 4,893.4(3) A3 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.
