CeLaAl2O6 is (Cubic) Perovskite-derived structured and crystallizes in the trigonal R32 space group. Ce(1) is bonded to six equivalent O(1) and six equivalent O(2) atoms to form CeO12 cuboctahedra that share corners with twelve equivalent Ce(1)O12 cuboctahedra, faces with six equivalent La(1)O12 cuboctahedra, and faces with eight equivalent Al(1)O6 octahedra. La(1) is bonded to six equivalent O(1) and six equivalent O(2) atoms to form LaO12 cuboctahedra that share corners with twelve equivalent La(1)O12 cuboctahedra, faces with six equivalent Ce(1)O12 cuboctahedra, and faces with eight equivalent Al(1)O6 octahedra. Al(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form AlO6 octahedra that share corners with six equivalent Al(1)O6 octahedra, faces with four equivalent Ce(1)O12 cuboctahedra, and faces with four equivalent La(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 8-9°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to two equivalent Ce(1), two equivalent La(1), and two equivalent Al(1) atoms. In the second O site, O(2) is bonded in a 2-coordinate geometry to two equivalent Ce(1), two equivalent La(1), and two equivalent Al(1) atoms.
