Materials Data on Cs3SbBr6 by Materials Project
(Cs)2CsSbBr6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight cesium molecules and one CsSbBr6 framework. In the CsSbBr6 framework, Cs1+ is bonded to six equivalent Br1- atoms to form CsBr6 octahedra that share corners with six equivalent SbBr6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Cs–Br bond lengths are 3.41 Å. Sb3+ is bonded to six equivalent Br1- atoms to form SbBr6 octahedra that share corners with six equivalent CsBr6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Sb–Br bond lengths are 2.82 Å. Br1- is bonded in a linear geometry to one Cs1+ and one Sb3+ atom.
