BaEuCeHfO6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic F-43m space group. Ba(1) is bonded to twelve equivalent O(1) atoms to form BaO12 cuboctahedra that share corners with twelve equivalent Ba(1)O12 cuboctahedra, faces with six equivalent Eu(1)O12 cuboctahedra, faces with four equivalent Ce(1)O6 octahedra, and faces with four equivalent Hf(1)O6 octahedra. Eu(1) is bonded to twelve equivalent O(1) atoms to form EuO12 cuboctahedra that share corners with twelve equivalent Eu(1)O12 cuboctahedra, faces with six equivalent Ba(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 Ba(1)O12 cuboctahedra, and faces with four equivalent Eu(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. 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 Ba(1)O12 cuboctahedra, and faces with four equivalent Eu(1)O12 cuboctahedra.
