• Polyoxometalates
• Ion exchange

A new mixed solvent procedure which allows the exchange of polyoxometalate (POM) alkali metal cations for tetrabutylammonium (TBA) and protons is presented. This method has been demonstrated for simple Keggin [PW12O40](3-) and Dawson [P2W18O62](6-) POMs as well as the larger phosphotungstates [Na subset of P5W30O110](14-) and [K-4 subset of P8W48O184](36-) for which no TBA salt has been previously reported.
