The structure described by ErHo is Magnesium-derived structured and crystallizes in the hexagonal P-6m2 space group. Er(1) is bonded to six equivalent Er(1) and six equivalent Ho(1) atoms to form ErHo6Er6 cuboctahedra that share corners with eighteen equivalent Er(1)Ho6Er6 cuboctahedra, edges with six equivalent Er(1)Ho6Er6 cuboctahedra, edges with twelve equivalent Ho(1)Ho6Er6 cuboctahedra, faces with eight equivalent Er(1)Ho6Er6 cuboctahedra, and faces with twelve equivalent Ho(1)Ho6Er6 cuboctahedra.
