Abstract
We report on the feasibility of applying high-resolution solid-state 195Pt MAS NMR spectroscopy for several PtIV-containing polyoxotungstates, and of 195Pt as well as 51V for a PtIV-containing polyoxovanadate. This method is particularly useful for polyanions which are unstable in solution and/or poorly soluble, as well as for systems exhibiting crystallographic disorder of Pt and W sites. We also report solution 195Pt and 183W NMR spectra of hexatungstoplatinate(iv) [H<inf>3</inf>PtW<inf>6</inf>O<inf>24</inf>]5- for the first time. © The Royal Society of Chemistry and the Centre National de la Recherche Scientifique 2016.
