ErHo3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Er(1) is bonded to twelve equivalent Ho(1) atoms to form ErHo12 cuboctahedra that share corners with twelve equivalent Er(1)Ho12 cuboctahedra, edges with twenty-four equivalent Ho(1)Ho8Er4 cuboctahedra, faces with six equivalent Er(1)Ho12 cuboctahedra, and faces with twelve equivalent Ho(1)Ho8Er4 cuboctahedra. Ho(1) is bonded to four equivalent Er(1) and eight equivalent Ho(1) atoms to form HoHo8Er4 cuboctahedra that share corners with twelve equivalent Ho(1)Ho8Er4 cuboctahedra, edges with eight equivalent Er(1)Ho12 cuboctahedra, edges with sixteen equivalent Ho(1)Ho8Er4 cuboctahedra, faces with four equivalent Er(1)Ho12 cuboctahedra, and faces with fourteen equivalent Ho(1)Ho8Er4 cuboctahedra.
