Improving nuclear waste reprocessing to reduce the volume of material converted for long term storage remains a challenge. The use of polyoxometalate complexes for separation of actinide species from nuclear waste is a viable alternative. Polyoxometalates (POMs) are ligands composed of metal-oxygen anionic clusters composing of transition metals such as vanadium and tungsten in high oxidation states. POMs are immensely redox-active and have been shown to greatly affect the redox potential windows of lanthanides in solution. Herein, we report the synthesis and structural investigation of lanthanide and actinide complexes with various polyoxometalates.
