The crystal structure described by Al3Er is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. Er(1) is bonded to twelve equivalent Al(1) atoms to form ErAl12 cuboctahedra that share corners with twelve equivalent Er(1)Al12 cuboctahedra, edges with twenty-four equivalent Al(1)Er4Al8 cuboctahedra, faces with six equivalent Er(1)Al12 cuboctahedra, and faces with twelve equivalent Al(1)Er4Al8 cuboctahedra. Al(1) is bonded to four equivalent Er(1) and eight equivalent Al(1) atoms to form distorted AlEr4Al8 cuboctahedra that share corners with twelve equivalent Al(1)Er4Al8 cuboctahedra, edges with eight equivalent Er(1)Al12 cuboctahedra, edges with sixteen equivalent Al(1)Er4Al8 cuboctahedra, faces with four equivalent Er(1)Al12 cuboctahedra, and faces with fourteen equivalent Al(1)Er4Al8 cuboctahedra. is represented by the CIF card [CIF]
