Materials Data on Cs2AgAsBr6 by Materials Project
Cs2AgAsBr6 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 AsBr6 octahedra. All Cs–Br bond lengths are 3.93 Å. Ag1+ is bonded to six equivalent Br1- atoms to form AgBr6 octahedra that share corners with six equivalent AsBr6 octahedra and faces with eight equivalent CsBr12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ag–Br bond lengths are 2.86 Å. As3+ is bonded to six equivalent Br1- atoms to form AsBr6 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 As–Br bond lengths are 2.69 Å. Br1- is bonded to four equivalent Cs1+, one Ag1+, and one As3+ atom to form a mixture of distorted edge, corner, and face-sharing BrCs4AgAs octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
