Hydrothermal synthesis of a new perovskite-type bismuth oxide: Ba 0.96Bi0.86O2.59(OH)0.41

Abstract

A new perovskite-type oxide, Ba0.96Bi0.86O 2.59(OH)0.41 was prepared by low temperature hydrothermal reaction using NaBiO3·nH2O and Ba(OH) 2·8H2O as starting materials. The crystal structure of this compound was refined by single crystal X-ray diffraction data, and the structure refinement with the space group Pm3m (#221) led to Rw = 0.035 and R = 0.054 for all reflections. This compound had the perovskite-type structure with the cubic cell of a = 4.2995 (5) Å. The magnetic susceptibility of this compound exhibited no superconductive behavior down to 4 K. © 2009 The Ceramic Society of Japan. All rights reserved.
