Materials Data on YbCoO3 by Materials Project

Abstract

YbCoO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Yb3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Yb–O bond distances ranging from 2.30–2.54 Å. Co3+ is bonded to six O2- atoms to form corner-sharing CoO6 octahedra. The corner-sharing octahedra tilt angles range from 25–28°. There are a spread of Co–O bond distances ranging from 1.89–1.93 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent Yb3+ and two equivalent Co3+ atoms. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Yb3+ and two equivalent Co3+ atoms.
