cif-access (inorganic compounds)
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 W5O186- ligands, related by a crystallographic twofold axis through Ce, are therefore unprotonated.
