The structure described by LuTb crystallizes in the hexagonal P-6m2 space group. Lu(1) is bonded to six equivalent Lu(1) and six equivalent Tb(1) atoms to form LuTb6Lu6 cuboctahedra that share corners with eighteen equivalent Lu(1)Tb6Lu6 cuboctahedra, edges with six equivalent Lu(1)Tb6Lu6 cuboctahedra, edges with twelve equivalent Tb(1)Tb6Lu6 cuboctahedra, faces with eight equivalent Lu(1)Tb6Lu6 cuboctahedra, and faces with twelve equivalent Tb(1)Tb6Lu6 cuboctahedra.
