摘要：

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 R (3) over barc, with a=9.9839(2) angstrom and c = 11.8008(4) angstrom. 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 R (3) over barc with a = 9.9193(2) angstrom, c = 11.7473(5) angstrom and a = 9.9293(2) angstrom, c = 11.4188(5) angstrom, respectively. In addition, we report the crystal growth of a strontium bismuth oxyhydroxide, Sr-4(BiO6))(OH), isolated from a reactive Sr(OH)2 flux contained in sealed silver tubes. Sr-4(BiC6)(OH) crystallizes in the monoclinic space group, P2(1) with a = 6.9429(8) angstrom, b = 6.1286(7) angstrom, c = 9.2746(10) angstrom, and beta = 102.176(2)degrees. The structure consists of layers of connected SrOx. polyhedra, with isolated BiO6 octahedra located in every second Sr-O layer. (C) 2008 Elsevier Masson SAS. All rights reserved.
