Redetermination of Sodium [Bis(pentatungstato)cerate(IV)](8 -) 30-Hydrate, Na₈[Ce(W₅O₁₈)₂].30H₂O

Better data have enabled eight Na⁺ cations per [Ce(W₅O₁₈)₂]^8- anion to be identified, in contrast to the six found earlier [Iball et al. (1974). J. Chem. Soc. Dalton Trans. pp. 2021-2024]. The two W₅O₁₈^6- ligands, related by a crystallographic twofold axis through Ce, are therefore unprotonated.
