NpNdO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. Np(1) is bonded to twelve equivalent O(1) atoms to form NpO12 cuboctahedra that share corners with twelve equivalent Np(1)O12 cuboctahedra, faces with six equivalent Np(1)O12 cuboctahedra, and faces with eight equivalent Nd(1)O6 octahedra. Nd(1) is bonded to six equivalent O(1) atoms to form NdO6 octahedra that share corners with six equivalent Nd(1)O6 octahedra and faces with eight equivalent Np(1)O12 cuboctahedra. The corner-sharing octahedra are not tilted. O(1) is bonded in a linear geometry to four equivalent Np(1) and two equivalent Nd(1) atoms.
