Peroxoniobate species are found whenever niobium oxides are employed as photocatalysts or used to sequester radionuclides. The reactions of [Nb 6 O 19 ] 8− and [Nb 10 O 28 ] 6− with hydrogen peroxide each behave differently, and the first example of a peroxopolyoxoniobate species, [N(CH 3 ) 4 ] 5 [H 3 Nb 6 O 13 (O (I) 2 ) 6 ]⋅9.5 H 2 O, was structurally characterized (see picture; Nb gray, O red, H white).
