The structure described by TbHf crystallizes in the hexagonal P-6m2 space group. Tb(1) is bonded to six equivalent Tb(1) and six equivalent Hf(1) atoms to form TbTb6Hf6 cuboctahedra that share corners with eighteen equivalent Tb(1)Tb6Hf6 cuboctahedra, edges with six equivalent Tb(1)Tb6Hf6 cuboctahedra, edges with twelve equivalent Hf(1)Tb6Hf6 cuboctahedra, faces with eight equivalent Tb(1)Tb6Hf6 cuboctahedra, and faces with twelve equivalent Hf(1)Tb6Hf6 cuboctahedra. Hf(1) is bonded to six equivalent Tb(1) and six equivalent Hf(1) atoms to form HfTb6Hf6 cuboctahedra that share corners with eighteen equivalent Hf(1)Tb6Hf6 cuboctahedra, edges with six equivalent Hf(1)Tb6Hf6 cuboctahedra, edges with twelve equivalent Tb(1)Tb6Hf6 cuboctahedra, faces with eight equivalent Hf(1)Tb6Hf6 cuboctahedra, and faces with twelve equivalent Tb(1)Tb6Hf6 cuboctahedra. is represented by the CIF file [CIF]
