Rb2AgSbF6 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 Ag(1)F6 octahedra, and faces with four equivalent Sb(1)F6 octahedra. Ag(1) is bonded to six equivalent F(1) atoms to form AgF6 octahedra that share corners with six equivalent Sb(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Sb(1) is bonded to six equivalent F(1) atoms to form SbF6 octahedra that share corners with six equivalent Ag(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 Ag(1), and one Sb(1) atom to form a mixture of distorted corner, face, and edge-sharing FRb4AgSb octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
