Materials Data on PmNd by Materials Project

PmNd is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Pm is bonded to six equivalent Pm and six equivalent Nd atoms to form PmPm6Nd6 cuboctahedra that share corners with eighteen equivalent PmPm6Nd6 cuboctahedra, edges with six equivalent PmPm6Nd6 cuboctahedra, edges with twelve equivalent NdPm6Nd6 cuboctahedra, faces with eight equivalent PmPm6Nd6 cuboctahedra, and faces with twelve equivalent NdPm6Nd6 cuboctahedra. All Pm–Pm bond lengths are 3.67 Å. All Pm–Nd bond lengths are 3.69 Å. Nd is bonded to six equivalent Pm and six equivalent Nd atoms to form NdPm6Nd6 cuboctahedra that share corners with eighteen equivalent NdPm6Nd6 cuboctahedra, edges with six equivalent NdPm6Nd6 cuboctahedra, edges with twelve equivalent PmPm6Nd6 cuboctahedra, faces with eight equivalent NdPm6Nd6 cuboctahedra, and faces with twelve equivalent PmPm6Nd6 cuboctahedra.
