Materials Data on EuCoO3 by Materials Project

Abstract

EuCoO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.37–2.64 Å. Co3+ is bonded to six O2- atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedra tilt angles range from 24–27°. There are a spread of Co–O bond distances ranging from 1.95–1.98 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Eu3+ and two equivalent Co3+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Eu3+ and two equivalent Co3+ atoms.
