Abstract

An open hollow polyoxovanadate (POV) cage, V₁₄Nb₂P₈, has been successfully constructed using {Nb(V₅)} pentagons as building blocks. The POV cage features a crown-ether-like {V₄P₄O₈} opening that can selectively coordinate with Cs⁺ ions. Additionally, it has a hollow cavity that acts as a molecular container to accommodate size-appropriate organic molecules.
