| Abstract Scope |
Polyoxometalates (POMs) are a class of inorganic metal oxide clusters known for their rich redox chemistry, catalysis, and wide structure variability. They are typically composed of MO6 (M=W6+, Mo6+, V5+) octahedra ranging from 6 to 256 metals linked into discrete units by oxygen atoms. The oxygen atoms on the surface of POMs can act as ligands for chelation of transition and f-block elements making them useful for several applications including catalysis and nuclear waste decontamination. In this work, we report several Preyssler POM solids featuring chelation to Gd, Fe and Ni cations. Methods to study the stability of these POMs in the solid, aqueous, and molten salt environments was tested. In addition, the reduced oxidation state of these POMs is potentially useful for corrosion inhibition in both aqueous and molten salt environments.
