摘　　要：A new organic-inorganic hybrid based on tungstophosphate anions and benzotria- zole cations, [Na（BTA）E（H2O）2]2[{Cd（BTA）4（H2O）}2（P2W18O62）]·6H2O （1） （BTA = benzotriazole） has been synthesized in aqueous solution and characterized by elemental analysis, IR spectroscopy, thermal gravimetric analysis, and single-crystal X-ray diffraction. X-ray analysis showed that both {Na（BTA）2} and {Cd（BTA）4} units are supported on the a-Dawson polyoxoanion [P2W18062]6- via the surface bridging oxygen atoms. The electrochemical properties of 1 in aqueous solution are studied at room temperature. It was found that 1 presents good electrocatalytic activities for the reduction of NO2^-.A new organic-inorganic hybrid based on tungstophosphate anions and benzotria- zole cations, [Na（BTA）E（H2O）2]2[{Cd（BTA）4（H2O）}2（P2W18O62）]·6H2O （1） （BTA = benzotriazole） has been synthesized in aqueous solution and characterized by elemental analysis, IR spectroscopy, thermal gravimetric analysis, and single-crystal X-ray diffraction.
