采用拉曼光谱、红外光谱和x射线衍射（XRD）分析了金属钨和h2o水溶液制备的过氧化物钨酸（W- pta）的结构。W-PTA是一种由过氧多钨酸盐阴离子组成的无定形化合物，其中阴离子通过氢键相互结合。RDF分析表明，聚阴离子为W12O38(O2)16−6，其中一个由WO5（O2）或WO6等共角多面体组成的六元环被两个由WO6组成的w3o10单元夹在中间。
The structure of peroxotungstic acid (W-PTA) prepared from metallic W and aqueous H2O2was investigated based on Raman, IR, and XRD analyses. W-PTA was an amorphous compound constructed of peroxo polytungstate anions, in which the anions were bound to each other through hydrogen bonding. RDF analyses suggested that the polyanion was W12O38(O2)16−6, in which a six-membered ring of corner-shared polyhedra, such as WO5(O2) or WO6, was sandwiched by two W3O10units consisting of edge-shared WO6.
