Metal Complexes of Organophosphate Esters and Open-Framework Metal Phosphates: Synthesis, Structure, Transformations, and Applications


The chemistry of organophosphate ester complexes has been reviewed. Also included are the complexes that have been sufficiently well characterized through a single x-ray diffraction study, structural characterization of phosphate ester metal complex, and phosphate-based materials. Metal-containing aluminophosphate molecular sieves offer tremendous potential as heterogeneous catalysts for liquid-phase oxidation reactions in the production of fine chemicals. The recent success in the preparation of AlPO-based catalyst for the oxidation of n-alkanes at the terminal C atoms with high selectivity using molecular oxygen in liquid-phase reaction has been considered a breakthrough. Also notable is the observation of interesting magnetic properties. This transition metal containing open-framework solids show different types of magnetic ordering thus, classified as anti-ferromagnetic materials. These metal ions also exhibit interesting magnetic exchange between the metal phosphate layers via the organic linkers.
