K2TiCuF6 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 Ti(1)F6 octahedra, and faces with four equivalent Cu(1)F6 octahedra. Ti(1) is bonded to six equivalent F(1) atoms to form TiF6 octahedra that share corners with six equivalent Cu(1)F6 octahedra and faces with eight equivalent K(1)F12 cuboctahedra. The corner-sharing octahedra are not tilted. Cu(1) is bonded to six equivalent F(1) atoms to form CuF6 octahedra that share corners with six equivalent Ti(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 Ti(1), and one Cu(1) atom.
