Abstract: The title compounds have been prepared by dissolving sodium niobate(or sodium tantalate) and sodium tungstate in 30% hydrogen peroxide solution at -5 ℃ and adjusting pH=1 with hydrochloric acid. The results of elementary analysis, TG-DTG, IR, UV and XPS indicate that the title compounds have the hexametaiate type structure, and the O22- group is coordinated with niobium or tantalum.

Key words: Peroxo-niobotungstate, Peroxo-tantalotungstate, Synthesis, Characterization
