A Peanut‐Like Sb‐Embedded Polyoxoniobate Cage for Hydrolytic Decomposition of Chemical Warfare Agent

A Sb‐embedded polyoxoniobate has been originally synthesized under hydrothermal conditions. Particularly, the peanut‐like [Sb2Nb24O72]18− cluster cage in 1 with C2h symmetry is composed of two 9‐nuclear {SbNb9O33} motifs and one {Nb6O24} crown‐shaped ring. The compound 1 present the novel structure...

Summary:A Sb‐embedded polyoxoniobate has been originally synthesized under hydrothermal conditions. Particularly, the peanut‐like [Sb2Nb24O72]18− cluster cage in 1 with C2h symmetry is composed of two 9‐nuclear {SbNb9O33} motifs and one {Nb6O24} crown‐shaped ring. The compound 1 present the novel structure of Sb‐substituted sandwich‐type polyoxoniobate with antimoniobate cluster cage. Decomposition catalytic studies indicate that compound 1 exhibits good hydrolytic activity and stability on the degradation of nerve agent simulant dimethylphosphonate (DMMP). A Sb‐embedded polyoxoniobate, H4Na8K6[Sb2Nb24O72] ⋅ 30H2O, composed of the largest peanut‐like antimony‐niobate cluster cage with C2h symmetry, exhibits good hydrolytic activity and stability in the degradation of nerve agent simulant DMMP.
