Trigonal sodium cal­cium germanate, Na_2.54Ca_1.73Ge₃O₉

A new sodium calcium germanate with the formula Na_2.54Ca_1.73Ge₃O₉ has been synthesized by the flux method. The structure consists of six-membered rings of GeO₄ tetrahedra and pseudo-cubic subcells with an edge length of 3.8 Å.

Ca₄IrO₆, Ca₃MgIrO₆ and Ca₃ZnIrO₆

Crystals of the title compounds were grown from a eutectic halide flux. They are isostructural with K₄CdCl₆ and contain chains of face-shared [IrO₆] octahedra and [MO₆] trigonal prisms (M is Ca, Mg or Zn).

Potassium silver tin selenide, K₂Ag₂Sn₂Se₆

The structure of K₂Ag₂Sn₂Se₆ is composed of [Ag₂Sn₂Se₆]²⁻ anionic chains separated by K⁺ cations.

Potassium oxo­antimonate(V), K₃[SbO₄]

The oxoantimonate K₃[SbO₄] has the Na₃[BiO₄] structure type, with chains of [SbO₆] octahedra connected via common edges.
