Crystalline assembly of metal–organic polyhedra driven by ionic interactions with polyoxometalates

Abstract

Charge-driven self-assembly of cationic zirconium-based metal–organic polyhedra (MOPs) with polyoxometalates (POMs) leads to a series of porous crystalline salts, prepared by simple mixing of soluble precursors. The reactivity of immobilized POMs was greatly increased, as demonstrated by their fast reduction by hydrazine vapors, without loss of structural integrity.
