NdO2 is Hydrophilite structured and crystallizes in the monoclinic P2_1/c space group. Nd(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form a mixture of corner and edge-sharing NdO6 octahedra. The corner-sharing octahedral tilt angles range from 52-54°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to three equivalent Nd(1) atoms. In the second O site, O(2) is bonded in a trigonal planar geometry to three equivalent Nd(1) atoms.
