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.

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°. There are four shorter (2.36 Å) and two longer (2.46 Å) Nd(1)-O(1) bond lengths. 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°. All Nd(2)-O(1) bond lengths are 2.40 Å. 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.
