La2O3 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. There are two inequivalent La sites. In the first La site, La(1) is bonded to twelve equivalent O(1) atoms to form LaO12 cuboctahedra that share corners with twelve equivalent La(1)O12 cuboctahedra, faces with six equivalent La(1)O12 cuboctahedra, and faces with eight equivalent La(2)O6 octahedra. In the second La site, La(2) is bonded to six equivalent O(1) atoms to form LaO6 octahedra that share corners with six equivalent La(2)O6 octahedra and faces with eight equivalent La(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent La(2) and four equivalent La(1) atoms.
