Materials Data on SrBiO3 by Materials Project

Abstract

SrBiO3 is Orthorhombic Perovskite structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Sr–O bond distances ranging from 2.52–3.10 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 32–36°. There are two shorter (2.33 Å) and four longer (2.35 Å) Bi–O bond lengths. 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 32–36°. There are four shorter (2.17 Å) and two longer (2.18 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 Sr and two Bi atoms. In the second O site, O is bonded in a 5-coordinate geometry to three equivalent Sr and two Bi atoms. In the third O site, O is bonded to two equivalent Sr and two Bi atoms to form distorted corner-sharing OSr2Bi2 tetrahedra.
