The material described by Al7CoCu2 crystallizes in the tetragonal P4/mnc space group. Co(1) is bonded in a 9-coordinate geometry to one Al(1), four equivalent Al(2), and four equivalent Al(3) atoms. Cu(1) is bonded in a 10-coordinate geometry to two equivalent Cu(1), two equivalent Al(1), and six equivalent Al(3) atoms. There are three inequivalent Al sites. In the first Al site, Al(1) is bonded in a 5-coordinate geometry to one Co(1) and four equivalent Cu(1) atoms. In the second Al site, Al(2) is bonded in a distorted bent 150 degrees geometry to two equivalent Co(1) atoms. In the third Al site, Al(3) is bonded in a 4-coordinate geometry to one Co(1) and three equivalent Cu(1) atoms. is represented by the CIF file [CIF]
