The structure described by ErTb3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Er(1) is bonded to twelve equivalent Tb(1) atoms to form ErTb12 cuboctahedra that share corners with twelve equivalent Er(1)Tb12 cuboctahedra, edges with twenty-four equivalent Tb(1)Tb8Er4 cuboctahedra, faces with six equivalent Er(1)Tb12 cuboctahedra, and faces with twelve equivalent Tb(1)Tb8Er4 cuboctahedra. Tb(1) is bonded to four equivalent Er(1) and eight equivalent Tb(1) atoms to form TbTb8Er4 cuboctahedra that share corners with twelve equivalent Tb(1)Tb8Er4 cuboctahedra, edges with eight equivalent Er(1)Tb12 cuboctahedra, edges with sixteen equivalent Tb(1)Tb8Er4 cuboctahedra, faces with four equivalent Er(1)Tb12 cuboctahedra, and faces with fourteen equivalent Tb(1)Tb8Er4 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
