Trisilver oxoruthenate(V), Ag₃RuO₄

Ag₃RuO₄ contains Ru in the +5 oxidation state, octahedrally coordinated by oxygen. The RuO₆ octahedra are linked via common edges, resulting in polyanionic helical chains separated by Ag^I cations.

Tetrapotassium dicarbonato­dioxo­peroxo­uranium(VI) 2.5-hydrate, K₄[U(CO₃)₂O₂(O₂)]·2.5H₂O

The title compound contains individual [UO₂(O₂)(CO₃)₂]⁴⁻ ions in which the U atom is coordinated to two trans-axial O atoms and six O atoms in the equatorial plane, forming distorted hexagonal bipyramids.

Doubled-cubic Ca₂NF

Doubling of the cubic lattice of the title compound relative to the rocksalt-type phase reported previously is due to ordering of N and F atoms along all three cell axes. Residual electron density at an interstitial tetrahedral site was refined as a Frenkel defect of F atoms.
