Graphical Abstract

Thumbnail image of graphical abstract

Nude or neutralized? Small-angle X-ray Scattering (SAXS) measurements provide direct observation of contact ion pairing between the [Nb6O19]8− polyoxometalate and its eight charge-balancing cesium cations in aqueous solution. The radius of gyration (Rg) for Cs8[Nb6O19] and [Nb6O19]8− is shown.
