Wells-Dawson-type polyoxometalate

The formation of sandwich-type POMs from solutions of metal cations and triva-cant heteropolytungstate species may alternatively be viewed as means to sequester cations from solution [116]. The question then arises if reversible dissociation of the metal cations from the multidentate ligands is possible as well. The sequestration and subsequent release of metal cations under appropriate conditions is of considerable interest in waste decontamination technology as well as in medicine [124]. Following these ideas, the demetallation process of ten multi-iron Wells-Dawson polyoxometalates is studied by cyclic... [Pg.658]

The reducibility of type-I polyoxometalates, notably the Keggin, Wells-Dawson, and Lindqvist (hexametalate) structures, to mixed-valence heteropoly blues was well established in the 1960s and... [Pg.663]
