Synthesis, Structure, and Characterization of the Hexagonal Provskite Ba5In0.93Mn4O14.40

Ba5In0.93Mn4O14.40 was synthesized in air at 1300 °C by traditional solid state reaction and structurally characterized using powder X-ray diffraction, neutron diffraction, and selected area electron diffraction (SAED). It crystallizes in the hexagonal space group P63/mmc with a = 5.7389(1) A and c = 23.6418(1) A and was formed by pseudoclose-packed BaO3−x layers in a sequence of (cchhh)2 with In and Mn cations occupying the oxygen octahedral holes.
