ErAl2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. Er(1) is bonded in a 16-coordinate geometry to four equivalent Er(1) and twelve equivalent Al(1) atoms. Al(1) is bonded to six equivalent Er(1) and six equivalent Al(1) atoms to form a mixture of face, corner, and edge-sharing AlEr6Al6 cuboctahedra.
