HfNd crystallizes in the hexagonal P-6m2 space group. Nd(1) is bonded to six equivalent Nd(1) and six equivalent Hf(1) atoms to form NdNd6Hf6 cuboctahedra that share corners with eighteen equivalent Nd(1)Nd6Hf6 cuboctahedra, edges with six equivalent Nd(1)Nd6Hf6 cuboctahedra, edges with twelve equivalent Hf(1)Nd6Hf6 cuboctahedra, faces with eight equivalent Nd(1)Nd6Hf6 cuboctahedra, and faces with twelve equivalent Hf(1)Nd6Hf6 cuboctahedra. Hf(1) is bonded to six equivalent Nd(1) and six equivalent Hf(1) atoms to form HfNd6Hf6 cuboctahedra that share corners with eighteen equivalent Hf(1)Nd6Hf6 cuboctahedra, edges with six equivalent Hf(1)Nd6Hf6 cuboctahedra, edges with twelve equivalent Nd(1)Nd6Hf6 cuboctahedra, faces with eight equivalent Hf(1)Nd6Hf6 cuboctahedra, and faces with twelve equivalent Nd(1)Nd6Hf6 cuboctahedra.
