The material structure described by YbCu5Al7 crystallizes in the orthorhombic Imm2 space group. Yb(1) is bonded in a 20-coordinate geometry to two equivalent Cu(2), eight equivalent Cu(1), one Al(1), one Al(2), two equivalent Al(3), two equivalent Al(4), and four equivalent Al(5) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 12-coordinate geometry to two equivalent Yb(1), one Cu(2), two equivalent Cu(1), one Al(1), one Al(2), one Al(4), two equivalent Al(3), and two equivalent Al(5) atoms. In the second Cu site, Cu(2) is bonded in a 12-coordinate geometry to two equivalent Yb(1), four equivalent Cu(1), two equivalent Al(2), two equivalent Al(3), and two equivalent Al(5) atoms. There are five inequivalent Al sites. In the first Al site, Al(1) is bonded in a 10-coordinate geometry to one Yb(1), four equivalent Cu(1), one Al(2), two equivalent Al(4), and two equivalent Al(5) atoms. In the second Al site, Al(2) is bonded in a 8-coordinate geometry to one Yb(1), two equivalent Cu(2), four equivalent Cu(1), one Al(1), and two equivalent Al(5) atoms.
