Materials Data on Cs2CeO3 by Materials Project

Abstract

Cs2CeO3 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional. Cs1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cs–O bond distances ranging from 3.01–3.45 Å. Ce4+ is bonded in a 5-coordinate geometry to five O2- atoms. There are a spread of Ce–O bond distances ranging from 2.05–2.28 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Cs1+ and two equivalent Ce4+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to four equivalent Cs1+ and one Ce4+ atom.
