Materials Data on Cs2O3 by Materials Project

Abstract

Cs2O3 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. there are two inequivalent Cs sites. In the first Cs site, Cs is bonded to twelve equivalent O atoms to form CsO12 cuboctahedra that share corners with twelve equivalent CsO12 cuboctahedra, faces with six equivalent CsO12 cuboctahedra, and faces with eight equivalent CsO6 octahedra. All Cs–O bond lengths are 3.28 Å. In the second Cs site, Cs is bonded to six equivalent O atoms to form CsO6 octahedra that share corners with six equivalent CsO6 octahedra and faces with eight equivalent CsO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Cs–O bond lengths are 2.32 Å. O is bonded in a distorted linear geometry to six Cs atoms.
