Nude or neutralized? Small‐angle X‐ray Scattering (SAXS) measurements provide direct observation of contact ion pairing between the [Nb 6 O 19 ] 8− polyoxometalate and its eight charge‐balancing cesium cations in aqueous solution. The radius of gyration ( R g ) for Cs 8 [Nb 6 O 19 ] and [Nb 6 O 19 ] 8− is shown.
