Materials Data on SrRhO3 by Materials Project

Abstract

SrRhO3 is Orthorhombic Perovskite-like structured and crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Sr2+ is bonded in a 11-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.42–2.84 Å. Rh4+ is bonded to six O2- atoms to form corner-sharing RhO6 octahedra. The corner-sharing octahedra tilt angles range from 22–27°. There are four shorter (2.04 Å) and two longer (2.05 Å) Rh–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+ and two equivalent Rh4+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Sr2+ and two equivalent Rh4+ atoms.
