      By introducing mixed-ligands en and ox, Cu²⁺ and different polyoxotungstates as synthons, two new polyoxotungstate-based inorganic-organic hybrid compounds {[Cu₂ (en) &#8322 (ox)][HPW₁₂O₄₀]} · (en) ₂ · 2H₂O (1) and {[Cu₂ (en) ₂ (ox)] [H₃BW₁₂O₄₀]} · (en) ₂ · 2H₂O (2) (en = ethylenediamine and ox = oxalate), were obtained in identical hydrothermal conditions and further characterized by elemental analyses, IR spectroscopy and single-crystal X-ray diffraction. Structural analyses revealed that both compounds are isostructural, and show one-dimensional (1D) chain constructed by [XW₁₂O₄₀]n− (X = P 1, B 2) Keggin-type polyoxoanions and [Cu₂ (en) ₂ (ox)] ²⁺ dinuclear copper subunits. The electrochemical experiments indicated that 1-based carbon paste electrode possesses high catalytic efficiency and selectivity towards reduction of H₂O₂, and thus 1 has potential to detect H₂O₂.
