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.
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. The Dy(1)-Cu(2) bond length is 2.90 Å. All Dy(1)-Cu(1) bond lengths are 2.90 Å. There are two shorter (3.17 Å) and four longer (3.21 Å) Dy(1)-Al(1) bond lengths. 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. All Cu(2)-Al(1) bond lengths are 2.58 Å. 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. All Cu(1)-Al(1) bond lengths are 2.75 Å. 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. Both Al(1)-Al(1) bond lengths are 2.83 Å.
