Materials Data on BiRhO3 by Materials Project
BiRhO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Rh3+ is bonded to six O2- atoms to form corner-sharing RhO6 octahedra. The corner-sharing octahedra tilt angles range from 37–40°. There are a spread of Rh–O bond distances ranging from 2.08–2.12 Å. Bi3+ is bonded in a 4-coordinate geometry to eight O2- atoms. There are a spread of Bi–O bond distances ranging from 2.26–2.73 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent Rh3+ and three equivalent Bi3+ atoms. In the second O2- site, O2- is bonded to two equivalent Rh3+ and two equivalent Bi3+ atoms to form distorted corner-sharing OBi2Rh2 trigonal pyramids.
