Abstract
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⊂P5W30O110]14− and [K4⊂P8W48O184]36− for which no TBA salt has been previously reported.
Graphical abstractPreviously inaccessible organic-soluble salts of large polyoxometalates with high charge density were prepared through a general mixed water/acetonitrile solvent-mediated cation exchange method.Figure optionsDownload full-size imageDownload as PowerPoint slide
