Dy5Au2Sb crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a distorted trigonal planar geometry to one Au(1) and two equivalent Sb(1) atoms. In the second Dy site, Dy(2) is bonded in a square co-planar geometry to four equivalent Au(1) atoms. Au(1) is bonded to two equivalent Dy(1), two equivalent Dy(2), and one Au(1) atom to form distorted corner-sharing AuDy4Au trigonal bipyramids. Sb(1) is bonded in a 8-coordinate geometry to eight equivalent Dy(1) atoms.
Dy5Au2Sb crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a distorted trigonal planar geometry to one Au(1) and two equivalent Sb(1) atoms. The Dy(1)-Au(1) bond length is 2.91 Å. Both Dy(1)-Sb(1) bond lengths are 3.12 Å. In the second Dy site, Dy(2) is bonded in a square co-planar geometry to four equivalent Au(1) atoms. All Dy(2)-Au(1) bond lengths are 2.91 Å. Au(1) is bonded to two equivalent Dy(1), two equivalent Dy(2), and one Au(1) atom to form distorted corner-sharing AuDy4Au trigonal bipyramids. The Au(1)-Au(1) bond length is 2.67 Å. Sb(1) is bonded in a 8-coordinate geometry to eight equivalent Dy(1) atoms.
