DyCuIn crystallizes in the hexagonal P-62m space group. Dy(1) is bonded in a 11-coordinate geometry to one Cu(1), four equivalent Cu(2), and six equivalent In(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 9-coordinate geometry to three equivalent Dy(1) and six equivalent In(1) atoms. In the second Cu site, Cu(2) is bonded in a 9-coordinate geometry to six equivalent Dy(1) and three equivalent In(1) atoms. In(1) is bonded in a 10-coordinate geometry to six equivalent Dy(1), two equivalent Cu(1), and two equivalent Cu(2) atoms.
DyCuIn crystallizes in the hexagonal P-62m space group. Dy(1) is bonded in a 11-coordinate geometry to one Cu(1), four equivalent Cu(2), and six equivalent In(1) atoms. The Dy(1)-Cu(1) bond length is 3.05 Å. All Dy(1)-Cu(2) bond lengths are 2.98 Å. There are two shorter (3.17 Å) and four longer (3.30 Å) Dy(1)-In(1) bond lengths. There are two inequivalent Cu sites.
