TL;DR: The ease of substitution of phosphate into the central tetrahedral position suggests that other oxoanions can be similarly substituted, promising a richer set of structures in this class.

TL;DR: The exchange rates of water ligated to Co(II) atoms in two polyoxotungstate sandwich molecules using the (17)O-NMR-based Swift-Connick method are reported and the molecules are clearly stable and monospecific in slightly acidic solutions, but dissociate in strongly acidic solutions.

TL;DR: NMR spectroscopy shows that the uranyl(VI) cluster investigated here is approximately 2 nm in diameter, contains 24 uranyl moieties, and 12 pyrophosphate units and has two distinct forms that interconvert in milliseconds to seconds depending on the temperature and the size of the counterions.

TL;DR: It is seen that some sites change enormously with pH, whereas other, similarly coordinated oxygen atoms are less affected, suggesting that either some protons are exchanging so rapidly that the oxygen sites are seeing an averaged charge, or that counterions are modulating the effect of the coordinated protons.

TL;DR: The inexpensive probe design doubles the current pressure range available for solution NMR spectroscopy and is particularly important to advance the field of aqueous geochemistry.
