KCeLaHfO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic F-43m space group. K(1) is bonded to twelve equivalent O(1) atoms to form KO12 cuboctahedra that share corners with twelve equivalent K(1)O12 cuboctahedra, faces with six equivalent La(1)O12 cuboctahedra, faces with four equivalent Ce(1)O6 octahedra, and faces with four equivalent Hf(1)O6 octahedra. Ce(1) is bonded to six equivalent O(1) atoms to form CeO6 octahedra that share corners with six equivalent Hf(1)O6 octahedra, faces with four equivalent K(1)O12 cuboctahedra, and faces with four equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. La(1) is bonded to twelve equivalent O(1) atoms to form LaO12 cuboctahedra that share corners with twelve equivalent La(1)O12 cuboctahedra, faces with six equivalent K(1)O12 cuboctahedra, faces with four equivalent Ce(1)O6 octahedra, and faces with four equivalent Hf(1)O6 octahedra. Hf(1) is bonded to six equivalent O(1) atoms to form HfO6 octahedra that share corners with six equivalent Ce(1)O6 octahedra, faces with four equivalent K(1)O12 cuboctahedra, and faces with four equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent K(1), one Ce(1), two equivalent La(1), and one Hf(1) atom.
