A new Zr-substituted polyoxotungstate, [H₂N(CH₃)₂]₁₁KNa₅H₇[Zr₄K₂(β-GeW₁₀O₃₈)₂(A-α-PW₉O₃₄)₂]·39H₂O (1), has been hydrothermally synthesized and characterized by single crystal X-ray diffraction, IR spectrum, UV–vis diffuse-reflectance spectrum, elemental analysis, powder X-ray diffraction, ICP-MS test and thermogravimetric analysis. The prominent feature of 1 is that mixed Keggin-type dilacunary [β-GeW₁₀O₃₈]¹²⁻ fragment and trilacunary [A-α-PW₉O₃₄]⁹⁻ fragment construct the basic framework of 1. And 1 displays special 1D double-chain and 2D thick layer formed by K⁺/Na⁺ ions. 1 exhibits well electrocatalytic behavior in the reduction of BrO₃⁻. Also, the experimental results of catalytic oxidation of representative thioethers manifest that 1 possesses a good catalytic capacity.
