“…HSQC assist in the assignment of NMR signals to specific nuclei in the cluster structure, which allows identification of different conformations of the phosphonic bridges. This work is particularly significant because the sets of such actinide clusters now extend to beyond >60 distinct molecules, [1,3] yet the dynamics of these ions in solution are poorly understood. Preliminary high-pressure NMR data indicates systematic changes in the population of phosphonic-bridge conformers, which will certainly also be affected by the choice of solution composition and counterions.…”

“…[2] Varieties are stable and soluble across the entire pH range of natural waters. [3] These clusters are particularly relevant to environmental chemistry because H 2 O 2 forms during the dissociation of water by radiolysis in repositories for radioactive waste. [4,5] Here we use the PHO 3 2-bridges in one unique set of such clusters to establish both the stabilities and dynamics in solution via Nuclear Magnetic Resonance (NMR) spectroscopy.…”

“…It can form a variety of compounds through chemical interactions with inorganic species and organic ligands. Inorganic uranium compounds, such as uranium minerals and oxides, fluorides, silicates, sulfates, phosphates, vanadates, and borates in synthesized phases, have been thoroughly investigated [1][2][3][4]. These materials are critically relevant to mining and extraction processes, to separations procedures, and to the long term storage of nuclear fuels [5,6].…”

“…In recent years, unconventional polyoxometalates (POMs) built from f-block (U, Np, Ce) [1] or noble-metal (Pd, Au, Pt) [2] addenda atoms have been reported. The building blocks of these nanoscopic species are different from the {MO 6 } octahedra defining classical POMs (with M = W, Mo, Nb, or V).…”
