Dalton communication. Solid-state nuclear magnetic resonance studies on the co-ordination geometry of boron in polyoxotungstates
Abstract
The co-ordination geometry of boron in derivatives of a polyoxotungstate with the Keggin structure, K5[BW12O40]·11 H2O, has been studied by solid-state magic-angle-spinning NMR spectroscopy (in tandem with Fourier-transform infrared spectroscopy) which is shown to be a sensitive tool for probing the immediate environment of 11B in polyoxotungstates, yielding new information on the local symmetry.
