Materials Data on SrRhO3 by Materials Project

Abstract

SrRhO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.45–2.73 Å. Rh4+ is bonded to six O2- atoms to form corner-sharing RhO6 octahedra. The corner-sharing octahedra tilt angles range from 24–27°. There are two shorter (2.03 Å) and four longer (2.04 Å) Rh–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Sr2+ and two equivalent Rh4+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+ and two equivalent Rh4+ atoms.
