Assembly of TeO₃^2– Ions Embedded in an Nb/O Cage with Selective Decolorization of Organic Dye

Abstract

A novel 24-niobic-2-tellurite, [H₂Te₂Nb₂₄O₇₂]^14-, was isolated by incorporating tellurite anions into a polyoxoniobate cage. The synthesized cluster represents the first example of a sandwich-type polyoxoniobate with the largest telluroniobate aggregate. Furthermore, the hybrid material acts as an efficient catalyst for the decolorization of basic fuchsin.
