Materials Data on BaBiO3 by Materials Project

Abstract

BaBiO3 is Orthorhombic Perovskite structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ba is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Ba–O bond distances ranging from 2.75–3.29 Å. There are two inequivalent Bi sites. In the first Bi site, Bi is bonded to six O atoms to form corner-sharing BiO6 octahedra. The corner-sharing octahedra tilt angles range from 19–23°. All Bi–O bond lengths are 2.17 Å. In the second Bi site, Bi is bonded to six O atoms to form corner-sharing BiO6 octahedra. The corner-sharing octahedra tilt angles range from 19–23°. There are two shorter (2.31 Å) and four longer (2.32 Å) Bi–O bond lengths. There are three inequivalent O sites. In the first O site, O is bonded in a 5-coordinate geometry to three equivalent Ba and two Bi atoms. In the second O site, O is bonded in a 5-coordinate geometry to three equivalent Ba and two Bi atoms. In the third O site, O is bonded in a 5-coordinate geometry to three equivalent Ba and two Bi atoms.
