Synthesis and H conductivity of a new oxyhydride Ba2YHO3 with anion-ordered rock-salt layers

Author affiliations

Abstract

A new layered perovskite oxyhydride Ba2YHO3 was synthesized via high pressure synthesis. Powder X-ray and neutron diffraction experiments revealed that in Ba2YHO3 the ordered H and O2− anions form [Ba2H2] rock-salt layers wherein H conduction is allowed. The conductivity reached 0.1 mS cm−1 at 350 °C, which is higher than that of isostructural Ba2ScHO3 with anion-disordered [Ba2HO] layers.
