C. Boskovic et al., Lifting the lid on metatungstate. H-1 and W-183 NMR study of the six electron reduced anion [(H)(2){W-3(IV)(OH2)(3)}(W9O34)-O-VI(OH)(3)](3-), CHEM COMMUN, (6), 1999, pp. 533-534
The distribution of the eleven protons present in a six-electron reduced fo
rm of metatungstate, [(H)(2){W-3(IV)-(OH2)(3)}(W9O34)-O-VI(OH)(3)](3-), in
dry CD3CN is mapped by H-1 and W-183 NMR, allowing assessment of structural
changes which accompany reduction.
