Study of the state of heteropolyanions of Mo(Vl) and W(VI) with aluminum (III) and gallium (III) in aqueous solutions by the NMR method using27Al,71Ga, and other nuclei

1. From the17O,27Al,71Ga, and183W NMR spectra, we have established that the structure of heteropolyanions of dissolved heteropoly compounds K3[Al(OH)6;Mo6O18], K3[Ga(OH)6Mo6O18] and H5[GaW12O40] is retained in aqueous solutions. 2. The27Al(71Ga) NMR spectra are sufficiently characteristic for identification of anions of hexamolybdate and dodecatungstates of aluminum (gallium) in aqueous solutions.
