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.
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. All Cu(1)-Al(1) bond lengths are 2.48 Å. Al(1) is bonded to four equivalent Cu(1) atoms to form a mixture of corner and edge-sharing AlCu4 tetrahedra.
