Materials Data on SrRuO3 by Materials Project

Abstract

SrRuO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr2+ is bonded in a 12-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.51–3.00 Å. Ru4+ is bonded to six O2- atoms to form corner-sharing RuO6 octahedra. The corner-sharing octahedral tilt angles are 20°. There are a spread of Ru–O bond distances ranging from 2.01–2.03 Å. 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 Ru4+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to three equivalent Sr2+ and two equivalent Ru4+ atoms.
