K2NaRhF6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. K(1) is bonded to twelve equivalent F(1) atoms to form KF12 cuboctahedra that share corners with twelve equivalent K(1)F12 cuboctahedra, faces with six equivalent K(1)F12 cuboctahedra, faces with four equivalent Na(1)F6 octahedra, and faces with four equivalent Rh(1)F6 octahedra. Na(1) is bonded to six equivalent F(1) atoms to form NaF6 octahedra that share corners with six equivalent Rh(1)F6 octahedra and faces with eight equivalent K(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Rh(1) is bonded to six equivalent F(1) atoms to form RhF6 octahedra that share corners with six equivalent Na(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 four equivalent K(1), one Na(1), and one Rh(1) atom.
