Materials Data on Cs3YBr6 by Materials Project
Abstract
(Cs)2CsYBr6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight cesium-133 molecules and one CsYBr6 framework. In the CsYBr6 framework, Cs1+ is bonded to six equivalent Br1- atoms to form CsBr6 octahedra that share corners with six equivalent YBr6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Cs–Br bond lengths are 3.43 Å. Y3+ is bonded to six equivalent Br1- atoms to form YBr6 octahedra that share corners with six equivalent CsBr6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Y–Br bond lengths are 2.80 Å. Br1- is bonded in a linear geometry to one Cs1+ and one Y3+ atom.
