Rb2AuCuF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to twelve equivalent F(1) atoms to form RbF12 cuboctahedra that share corners with twelve equivalent Rb(1)F12 cuboctahedra, faces with six equivalent Rb(1)F12 cuboctahedra, faces with four equivalent Au(1)F6 octahedra, and faces with four equivalent Cu(1)F6 octahedra. Au(1) is bonded to six equivalent F(1) atoms to form AuF6 octahedra that share corners with six equivalent Cu(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Cu(1) is bonded to six equivalent F(1) atoms to form CuF6 octahedra that share corners with six equivalent Au(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded to four equivalent Rb(1), one Au(1), and one Cu(1) atom to form a mixture of distorted face, corner, and edge-sharing FRb4CuAu octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
