Single-crystal X-ray structure analysis revealed the precise structure of a Ce-encapsulated Preyssler-type phosphotungstate which was first synthesized by Pope et al. Antonio et al. reported that encapsulated Ce has a 3+ oxidation state and is redox-inactive, which is unlike other Ce-containing phosphotungstates. Therefore, precise structural analysis about Ce position is needed. The encapsulated Ce was located in one of the side cavities, and was coordinated to one H2O molecule. The position of Ce was similar to that of Y3+ and Eu3+ in similar compounds. This result, together with the bond valence sum calculation, provides additional evidence that the oxidation state of the redox-inactive Ce in the Preyssler-type compound is 3+.
