Sr(NO₃)₂ at 173K

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.

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 W₅O₁₈⁶⁻ ligands, related by a crystallographic twofold axis through the square antiprismatic CeO₈ group, are therefore unprotonated.

Bis(tetra-n-butylammonium) Bis(1,1-di­cyano­ethylene-2,2-di­thiolato)nickelate(II)

The structure is isomorphous with that of the bis(thioselenato) analog, with the Ni atom lying on a center of symmetry.
