BaCaCeGeO6 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 Ca(1)O12 cuboctahedra, faces with four equivalent Ce(1)O6 octahedra, and faces with four equivalent Ge(1)O6 octahedra. Ca(1) is bonded to twelve equivalent O(1) atoms to form CaO12 cuboctahedra that share corners with twelve equivalent Ca(1)O12 cuboctahedra, faces with six equivalent Ba(1)O12 cuboctahedra, faces with four equivalent Ce(1)O6 octahedra, and faces with four equivalent Ge(1)O6 octahedra. Ce(1) is bonded to six equivalent O(1) atoms to form CeO6 octahedra that share corners with six equivalent Ge(1)O6 octahedra, faces with four equivalent Ba(1)O12 cuboctahedra, and faces with four equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. Ge(1) is bonded to six equivalent O(1) atoms to form GeO6 octahedra that share corners with six equivalent Ce(1)O6 octahedra, faces with four equivalent Ba(1)O12 cuboctahedra, and faces with four equivalent Ca(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent Ba(1), two equivalent Ca(1), one Ce(1), and one Ge(1) atom.
