Materials Data on Cs2RbYBr6 by Materials Project
Cs2RbYBr6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent Br1- atoms to form CsBr12 cuboctahedra that share corners with twelve equivalent CsBr12 cuboctahedra, faces with six equivalent CsBr12 cuboctahedra, faces with four equivalent RbBr6 octahedra, and faces with four equivalent YBr6 octahedra. All Cs–Br bond lengths are 4.31 Å. Rb1+ is bonded to six equivalent Br1- atoms to form RbBr6 octahedra that share corners with six equivalent YBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Rb–Br bond lengths are 3.29 Å. Y3+ is bonded to six equivalent Br1- atoms to form YBr6 octahedra that share corners with six equivalent RbBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Y–Br bond lengths are 2.80 Å. Br1- is bonded in a distorted linear geometry to four equivalent Cs1+, one Rb1+, and one Y3+ atom.
