摘要：

A metal-organic framework based on Wells-Dawson polyoxometalate [As2W18O62](6-), Co-2(bpy)(3)(ox)(As2W18O62)center dot 2(H(2)bpy)center dot 2H(2)O (1) (bpy = 4,4'-bipyridine, ox = oxalate), has been synthesized hydrothermally by reacting Co(NO3)(2), 4,4'-bipyridine, oxalate and K6As2W18O62. Single-crystal X-ray diffraction reveals that compound 1 contains a 3D cationic host framework composed of oxalate-bridged binuclear secondary building unit and 4,4'-bipyridine linkers. The channels of the 3D host framework are occupied by Wells-Dawson [As2W18O62](6-) templates. Thermogravimetric analysis shows the host framework keeps high thermal stability up to 450 degrees C. Furthermore, the electrochemistry property of 1 has been studied. The result indicates 1 has good electrocatalytic activity toward the reduction of nitrite. (c) 2011 Elsevier B.V.
