Cs2AuSbI6 crystallizes in the cubic Fm-3m space group. The structure is three-dimensional. Cs1+ is bonded to twelve equivalent I1- atoms to form CsI12 cuboctahedra that share corners with twelve equivalent CsI12 cuboctahedra, faces with six equivalent CsI12 cuboctahedra, faces with four equivalent AuI6 octahedra, and faces with four equivalent SbI6 octahedra. All Cs–I bond lengths are 4.26 Å. Au1+ is bonded to six equivalent I1- atoms to form AuI6 octahedra that share corners with six equivalent SbI6 octahedra and faces with eight equivalent CsI12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Au–I bond lengths are 2.98 Å. Sb3+ is bonded to six equivalent I1- atoms to form SbI6 octahedra that share corners with six equivalent AuI6 octahedra and faces with eight equivalent CsI12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Sb–I bond lengths are 3.05 Å. I1- is bonded to four equivalent Cs1+, one Au1+, and one Sb3+ atom to form a mixture of distorted edge, corner, and face-sharing ICs4SbAu octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
