Materials Data on BaTbO3 by Materials Project
Abstract
BaTbO3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Ba2+ is bonded in a 3-coordinate geometry to nine O2- atoms. There are three shorter (2.73 Å) and six longer (3.15 Å) Ba–O bond lengths. Tb4+ is bonded to six O2- atoms to form corner-sharing TbO6 octahedra. The corner-sharing octahedra tilt angles range from 21–22°. All Tb–O bond lengths are 2.26 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Ba2+ and two equivalent Tb4+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Ba2+ and two equivalent Tb4+ atoms.
