Rb2MnHgF6 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 Mn(1)F6 octahedra, and faces with four equivalent Hg(1)F6 octahedra. Mn(1) is bonded to six equivalent F(1) atoms to form MnF6 octahedra that share corners with six equivalent Hg(1)F6 octahedra and faces with eight equivalent Rb(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Hg(1) is bonded to six equivalent F(1) atoms to form HgF6 octahedra that share corners with six equivalent Mn(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 Mn(1), and one Hg(1) atom to form a mixture of distorted corner, edge, and face-sharing FRb4MnHg octahedra. The corner-sharing octahedral tilt angles range from 0-60°.
