NaCeHf2O6 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Fm-3m space group. Na(1) is bonded to twelve equivalent O(1) atoms to form NaO12 cuboctahedra that share corners with twelve equivalent Na(1)O12 cuboctahedra, faces with six equivalent Ce(1)O12 cuboctahedra, and faces with eight equivalent Hf(1)O6 octahedra. Ce(1) is bonded to twelve equivalent O(1) atoms to form CeO12 cuboctahedra that share corners with twelve equivalent Ce(1)O12 cuboctahedra, faces with six equivalent Na(1)O12 cuboctahedra, and faces with eight 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 Hf(1)O6 octahedra, faces with four equivalent Na(1)O12 cuboctahedra, and faces with four equivalent Ce(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent Na(1), two equivalent Ce(1), and two equivalent Hf(1) atoms.
