The cyclic heteropolyanion, [P8W48O184]40- (abbreviated as {P8W48}), is an ideal building block for the construction of inherently porous framework materials, and a number of coordination polymers incorporating this polyoxometalate (POM) ligand have recently been prepared by exo-cyclic coordination of 1st-row transition metals (TMs) to produce MOFs based upon polyoxometalates. We describe here approaches to build all inorganic {P8W48}-based frameworks. These compounds are termed ‘POMzites’ to reflect the POM-based composition and zeolitic properties of each family member, although crucially, POMzites differ from zeolites in the modular nature of their preparation. As the synthesis of further POMzites is anticipated, the classification system and terminology introduced here will allow new compounds to be categorized and understood in the context of the established materials. Full mapping of the TM coordination sites of the {P8W48} ring may allow the targeted synthesis of new materials rather than the reliance on serendipity apparent in current methods.
