The crystal structure described by RbK2RuF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Rb(1) is bonded to six equivalent F(1) atoms to form RbF6 octahedra that share corners with six equivalent Ru(1)F6 octahedra and faces with eight equivalent K(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. K(1) is bonded to twelve equivalent F(1) atoms to form distorted KF12 cuboctahedra that share corners with twelve equivalent K(1)F12 cuboctahedra, faces with six equivalent K(1)F12 cuboctahedra, faces with four equivalent Rb(1)F6 octahedra, and faces with four equivalent Ru(1)F6 octahedra. Ru(1) is bonded to six equivalent F(1) atoms to form RuF6 octahedra that share corners with six equivalent Rb(1)F6 octahedra and faces with eight equivalent K(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. F(1) is bonded in a distorted linear geometry to one Rb(1), four equivalent K(1), and one Ru(1) atom. is represented by the CIF card [CIF]
