Materials Data on Cs2RbBiI6 by Materials Project
(Cs)2RbBiI6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional and consists of eight cesium molecules and one RbBiI6 framework. In the RbBiI6 framework, Rb1+ is bonded to six equivalent I1- atoms to form RbI6 octahedra that share corners with six equivalent BiI6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Rb–I bond lengths are 3.50 Å. Bi3+ is bonded to six equivalent I1- atoms to form BiI6 octahedra that share corners with six equivalent RbI6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Bi–I bond lengths are 3.08 Å. I1- is bonded in a linear geometry to one Rb1+ and one Bi3+ atom.
