The crystal structure described by UCu6Al5 crystallizes in the orthorhombic Fddd space group. U(1) is bonded in a 22-coordinate geometry to four equivalent Cu(1), eight equivalent Cu(2), two equivalent Al(1), and eight equivalent Al(2) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 10-coordinate geometry to two equivalent U(1), four equivalent Cu(2), two equivalent Al(1), and four equivalent Al(2) atoms. In the second Cu site, Cu(2) is bonded in a 12-coordinate geometry to two equivalent U(1), two equivalent Cu(1), two equivalent Cu(2), one Al(1), and five equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 14-coordinate geometry to two equivalent U(1), four equivalent Cu(1), four equivalent Cu(2), and four equivalent Al(2) atoms. In the second Al site, Al(2) is bonded in a 6-coordinate geometry to two equivalent U(1), two equivalent Cu(1), five equivalent Cu(2), and one Al(1) atom. is represented by the CIF card [CIF]
