PmNd is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. Pm(1) is bonded to six equivalent Pm(1) and six equivalent Nd(1) atoms to form PmPm6Nd6 cuboctahedra that share corners with eighteen equivalent Pm(1)Pm6Nd6 cuboctahedra, edges with six equivalent Pm(1)Pm6Nd6 cuboctahedra, edges with twelve equivalent Nd(1)Pm6Nd6 cuboctahedra, faces with eight equivalent Pm(1)Pm6Nd6 cuboctahedra, and faces with twelve equivalent Nd(1)Pm6Nd6 cuboctahedra. Nd(1) is bonded to six equivalent Pm(1) and six equivalent Nd(1) atoms to form NdPm6Nd6 cuboctahedra that share corners with eighteen equivalent Nd(1)Pm6Nd6 cuboctahedra, edges with six equivalent Nd(1)Pm6Nd6 cuboctahedra, edges with twelve equivalent Pm(1)Pm6Nd6 cuboctahedra, faces with eight equivalent Nd(1)Pm6Nd6 cuboctahedra, and faces with twelve equivalent Pm(1)Pm6Nd6 cuboctahedra.
