Nd2O3 is (Cubic) Perovskite-derived structured and crystallizes in the cubic Pm-3m space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to twelve equivalent O(1) atoms to form NdO12 cuboctahedra that share corners with twelve equivalent Nd(1)O12 cuboctahedra, faces with six equivalent Nd(1)O12 cuboctahedra, and faces with eight equivalent Nd(2)O6 octahedra. In the second Nd site, Nd(2) is bonded to six equivalent O(1) atoms to form NdO6 octahedra that share corners with six equivalent Nd(2)O6 octahedra and faces with eight equivalent Nd(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a distorted linear geometry to two equivalent Nd(2) and four equivalent Nd(1) atoms.
