Conversion of NO_x¹⁻ (<i>x</i> = 2, 3) to NO using an oxygen-deficient polyoxovanadate–alkoxide cluster

Abstract

We report the activation of nitrogen-containing oxyanions using an oxygen-deficient polyoxovanadate-alkoxide cluster. Reduction of NO₂^1- and NO₃^1- results in near-quantitative oxygen atom transfer to the coordinatively unsaturated V^III ion, and selective formation of NO. These results provide insight into possible mechanisms of oxyanion reduction by polyoxometalates.
