    High Pressure Synthesis of the Cation‐ordered Perovskite 3C1: 2‐Ba3NaRu2O9

    Angel M. Arevalo-Lopez, Mark S. Senn, Lauren Skedd and J. Paul Attfield, Zeitschrift für anorganische und allgemeine Chemie, 640 (2014), 1164–1167.

    The new phase 3C1:2-Ba3NaRu2O9 was synthesized by heating the hexagonal perovskite 6H-Ba3NaRu2O9 at 900 °C under a pressure of 9 GPa. 3C1:2-Ba3NaRu2O9 adopts the 1:2 B site-ordered cubic perovskite type structure [space group Pequation imagem1, cell parameters a = 5.8068(3) and c = 7.0652(5) Å] but a significant cation inversion between Na and Ru sites is found. No magnetic ordering transition is observed down to 2 K and 3C1:2-Ba3NaRu2O9 displays Pauli paramagnetism indicative of a metallic oxide with strong electron-electron correlations.
