Abstract

Abstract : High-resolution solid-state 195 Pt MAS NMR spectroscopy is a powerful technique for the characterization of Pt IV -containing polyoxometalates, as is demonstrated for several examples. Abstract : We report on the feasibility of applying high-resolution solid-state 195 Pt MAS NMR spectroscopy for several Pt IV -containing polyoxotungstates, and of 195 Pt as well as 51 V for a Pt IV -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 195 Pt and 183 W NMR spectra of hexatungstoplatinate(iv ) [H3 PtW6 O24 ] 5− for the first time.
