The crystal structure described by Nd2O3 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing NdO6 octahedra. The corner-sharing octahedral tilt angles range from 55-57°. In the second Nd site, Nd(2) is bonded to six equivalent O(1) atoms to form a mixture of distorted corner and edge-sharing NdO6 octahedra. The corner-sharing octahedral tilt angles are 57°. O(1) is bonded to one Nd(2) and three equivalent Nd(1) atoms to form a mixture of corner and edge-sharing ONd4 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
