The material structure described by Al2Cu is Fluorite structured and crystallizes in the tetragonal I4/mmm space group. Cu(1) is bonded in a body-centered cubic geometry to eight equivalent Al(1) atoms. Al(1) is bonded to four equivalent Cu(1) atoms to form a mixture of corner and edge-sharing AlCu4 tetrahedra. is represented by the CIF file [CIF]
