Materials Data on MnBiO3 by Materials Project

Abstract

BiMnO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mn3+ is bonded to six O2- atoms to form corner-sharing MnO6 octahedra. The corner-sharing octahedra tilt angles range from 33–35°. There are a spread of Mn–O bond distances ranging from 1.97–2.22 Å. Bi3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.30–2.76 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Mn3+ and two equivalent Bi3+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Mn3+ and three equivalent Bi3+ atoms.
