Abstract

The structure of peroxotungstic acid (W-PTA) prepared from metallic W and aqueous H₂O₂ was 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 W₃O₁₀ units consisting of edge-shared WO₆.
