Crystal Growth of Bismuth(V) Oxides from Hydroxide Fluxes
The first example of a 2 H-perovskite related A3A′BiO6 oxide, (Sr2.59Ba0.41)NaBiO6, with two different divalent cations on the A site, was synthesized in a reactive, mixed strontium-, barium-, sodium-hydroxide flux. (Sr2.59Ba0.41)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 Sr3LiBiO6 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.
