Materials Data on CsYbBr3 by Materials Project
CsYbBr3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-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, and faces with eight equivalent YbBr6 octahedra. All Cs–Br bond lengths are 4.06 Å. Yb2+ is bonded to six equivalent Br1- atoms to form YbBr6 octahedra that share corners with six equivalent YbBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Yb–Br bond lengths are 2.87 Å. Br1- is bonded in a distorted linear geometry to four equivalent Cs1+ and two equivalent Yb2+ atoms.
