The crystal structure described by BaTb crystallizes in the hexagonal P-6m2 space group. Ba(1) is bonded to six equivalent Ba(1) and six equivalent Tb(1) atoms to form BaBa6Tb6 cuboctahedra that share corners with eighteen equivalent Ba(1)Ba6Tb6 cuboctahedra, edges with six equivalent Ba(1)Ba6Tb6 cuboctahedra, edges with twelve equivalent Tb(1)Ba6Tb6 cuboctahedra, faces with eight equivalent Ba(1)Ba6Tb6 cuboctahedra, and faces with twelve equivalent Tb(1)Ba6Tb6 cuboctahedra. Tb(1) is bonded to six equivalent Ba(1) and six equivalent Tb(1) atoms to form TbBa6Tb6 cuboctahedra that share corners with eighteen equivalent Tb(1)Ba6Tb6 cuboctahedra, edges with six equivalent Tb(1)Ba6Tb6 cuboctahedra, edges with twelve equivalent Ba(1)Ba6Tb6 cuboctahedra, faces with eight equivalent Tb(1)Ba6Tb6 cuboctahedra, and faces with twelve equivalent Ba(1)Ba6Tb6 cuboctahedra. is represented by the CIF file [CIF]
