The material structure described by DyCuAl crystallizes in the hexagonal P-62m space group. Dy(1) is bonded in a 11-coordinate geometry to one Cu(2), four equivalent Cu(1), and six equivalent Al(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(2) is bonded in a 9-coordinate geometry to three equivalent Dy(1) and six equivalent Al(1) atoms. In the second Cu site, Cu(1) is bonded in a 9-coordinate geometry to six equivalent Dy(1) and three equivalent Al(1) atoms. Al(1) is bonded in a 12-coordinate geometry to six equivalent Dy(1), two equivalent Cu(1), two equivalent Cu(2), and two equivalent Al(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
