Rb2AgInBr6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent Br(1) atoms to form RbBr12 cuboctahedra that share corners with twelve equivalent Rb(1)Br12 cuboctahedra, faces with six equivalent Rb(1)Br12 cuboctahedra, faces with four equivalent Ag(1)Br6 octahedra, and faces with four equivalent In(1)Br6 octahedra. Ag(1) is bonded to six equivalent Br(1) atoms to form AgBr6 octahedra that share corners with six equivalent In(1)Br6 octahedra and faces with eight equivalent Rb(1)Br12 cuboctahedra. The corner-sharing octahedra are not tilted. In(1) is bonded to six equivalent Br(1) atoms to form InBr6 octahedra that share corners with six equivalent Ag(1)Br6 octahedra and faces with eight equivalent Rb(1)Br12 cuboctahedra. The corner-sharing octahedra are not tilted. Br(1) is bonded to four equivalent Rb(1), one Ag(1), and one In(1) atom to form a mixture of distorted corner, face, and edge-sharing BrRb4InAg octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
