Title: Materials Data on Cs2GaAgBr6 by Materials Project

Abstract

Cs2AgGaBr6 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 AgBr6 octahedra, and faces with four equivalent GaBr6 octahedra. All Cs–Br bond lengths are 3.89 Å. Ag1+ is bonded to six equivalent Br1- atoms to form AgBr6 octahedra that share corners with six equivalent GaBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ag–Br bond lengths are 2.89 Å. Ga3+ is bonded to six equivalent Br1- atoms to form GaBr6 octahedra that share corners with six equivalent AgBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ga–Br bond lengths are 2.61 Å. Br1- is bonded in a distorted linear geometry to four equivalent Cs1+, one Ag1+, and one Ga3+ atom.
