The material structure described by Rb2AuTlI6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent I(1) atoms to form RbI12 cuboctahedra that share corners with twelve equivalent Rb(1)I12 cuboctahedra, faces with six equivalent Rb(1)I12 cuboctahedra, faces with four equivalent Au(1)I6 octahedra, and faces with four equivalent Tl(1)I6 octahedra. Au(1) is bonded to six equivalent I(1) atoms to form AuI6 octahedra that share corners with six equivalent Tl(1)I6 octahedra and faces with eight equivalent Rb(1)I12 cuboctahedra. The corner-sharing octahedra are not tilted. Tl(1) is bonded to six equivalent I(1) atoms to form TlI6 octahedra that share corners with six equivalent Au(1)I6 octahedra and faces with eight equivalent Rb(1)I12 cuboctahedra. The corner-sharing octahedra are not tilted. I(1) is bonded to four equivalent Rb(1), one Au(1), and one Tl(1) atom to form a mixture of distorted corner, edge, and face-sharing IRb4TlAu octahedra. The corner-sharing octahedral tilt angles range from 0-60°. is represented by the CIF card [CIF]
