25. Although smaller isopolyanions and lacunary heteropolyanions exist, the smallest high-symmetry heteropolyanions present the Keggin structure shown in Figure 1. On the other hand, there are larger anions with 18, 30, 40 addenda atoms (ref 15c). One of the largest well-characterized polyoxotungstates known to date contains 48 tungsten atoms: (a) Constant, R.; Tézé, A. Inorg. Chem. 1985, 24, 4610-4.

52. The maximum observed for the "fractional" reduced species appears at a clearly different wavelength from that observed for the one-electron blue species. This could be explained by an intermolecular nature of the intervalence charge transfer processes taking place in the former case.
