Abstract

The first example of a 2 H-perovskite related A₃A′BiO₆ oxide, (Sr_2.59Ba_0.41)NaBiO₆, with two different divalent cations on the A site, was synthesized in a reactive, mixed strontium-, barium-, sodium-hydroxide flux. (Sr_2.59Ba_0.41)NaBiO₆ crystallizes in the space group R3¯c with a = 9.9839(2) Å and c = 11.8008(4) Å. Crystals of isostructural oxides, Sr₃NaBiO₆ and Sr₃LiBiO₆, were also obtained from reactive Sr(OH)₂, NaOH and LiOH fluxes. Sr₃NaBiO₆ and Sr_3LiBiO₆ crystallize in the space group R3¯c with a = 9.9193(2) Å, c = 11.7473(5) Å and a = 9.9293(2) Å, c = 11.4188(5) Å, respectively. In addition, we report the crystal growth of a strontium bismuthoxyhydroxide, Sr₄(BiO₆)(OH), isolated from a reactive Sr(OH)₂ flux contained in sealed silver tubes. Sr₄(BiO₆)(OH) crystallizes in the monoclinic space group, P21 with a = 6.9429(8) Å, b = 6.1286(7) Å, c = 9.2746(10) Å, and β = 102.176(2)°. The structure consists of layers of connected SrOx polyhedra, with isolated BiO6 octahedra located in every second Sr–O layer.
