Cerium oxide nanoclusters: commensurate with concepts of polyoxometalate chemistry?

The mixed-valent cerium(III/IV) oxide clusters {Ce-10} and {Ce-22}, derived from condensation reactions of cerium carboxylate coordination polymers, exhibit molecular growth tendencies similar to those of 'classical' group V and VI polyoxometalates, but with increasing nuclearity approach the structure of the parental oxide, CeO2.
