Molecular precursors to vanadyl pyrophosphate and vanadyl phosphite

A novel method of synthesizing single molecular cluster precursor species to vanadyl pyrophosphate and vanadyl phosphite was established through decomposition by pyrolysis. The design featured cluster synthetic and thermal chemistry that provide 'slosh and burn' pathway to maleic anhydride catalysts using vanadyl (IV) sulfate as starting material. Crystal structure analysis have demonstrated that the clusters tetra-anions were conserved with the same metrics.
