CeLaAl2O6 is (Cubic) Perovskite-derived structured and crystallizes in the orthorhombic Imm2 space group. Ce(1) is bonded to two equivalent O(1), two equivalent O(2), and eight equivalent O(3) 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 two equivalent O(1), two equivalent O(2), and eight equivalent O(3) 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 one O(1), one O(2), and four equivalent O(3) 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 are 1°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear 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 distorted linear geometry to two equivalent Ce(1), two equivalent La(1), and two equivalent Al(1) atoms. In the third O site, O(3) is bonded in a distorted linear geometry to two equivalent Ce(1), two equivalent La(1), and two equivalent Al(1) atoms.
