The material structure described by Rb2CuF6 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, and faces with four equivalent Cu(1)F6 octahedra. Cu(1) is bonded to six equivalent F(1) atoms to form CuF6 octahedra that share faces with eight equivalent Rb(1)F12 cuboctahedra. F(1) is bonded in a single-bond geometry to four equivalent Rb(1) and one Cu(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
