The structure described by ErDyMn4 is Hexagonal Laves-derived structured and crystallizes in the monoclinic C2/m space group. Er(1) is bonded in a 16-coordinate geometry to three equivalent Er(1), one Dy(1), three equivalent Mn(2), three equivalent Mn(4), and six equivalent Mn(3) atoms. Dy(1) is bonded in a 16-coordinate geometry to one Er(1), three equivalent Dy(1), three equivalent Mn(1), three equivalent Mn(4), and six equivalent Mn(3) atoms. There are four inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to six equivalent Dy(1), two equivalent Mn(4), and four equivalent Mn(3) atoms to form MnDy6Mn6 cuboctahedra that share corners with four equivalent Mn(4)Dy3Er3Mn6 cuboctahedra, corners with eight equivalent Mn(3)Dy3Er3Mn6 cuboctahedra, edges with six equivalent Mn(1)Dy6Mn6 cuboctahedra, faces with two equivalent Mn(2)Er6Mn6 cuboctahedra, faces with six equivalent Mn(4)Dy3Er3Mn6 cuboctahedra, and faces with twelve equivalent Mn(3)Dy3Er3Mn6 cuboctahedra.
