cif-access (inorganic compounds)

 

Sr(NO₃)₂ at 173K

B. El-Bali and M. Bolte

Synopsis: The structure of strontium nitrate, originally determined with neutron radiation at room temperature [Nowotny & Heger (1983). Acta Cryst. C39, 952-956], has been redetermined using X-ray analysis at 173 K.

Formula: Sr(NO₃)₂

 

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

C. Rosu and T. J. R. Weakley

Synopsis: 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 the square antiprismatic CeO₈ group, are therefore unprotonated.

Formula: Na₈[Ce(W₅O₁₈)₂].30H₂O
