Direct Observation of Contact Ion-Pair Formation in Aqueous Solution

Direct Observation of Contact Ion-Pair Formation in Aqueous Solution

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....

Zusammenfassung: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.
