YbDy2Au crystallizes in the trigonal R3m space group. Yb(1) is bonded to one Dy(2) and three equivalent Au(1) atoms to form distorted corner-sharing YbDyAu3 trigonal pyramids. The Yb(1)-Dy(2) bond length is 1.86 Å. All Yb(1)-Au(1) bond lengths are 3.08 Å. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a single-bond geometry to one Au(1) atom. The Dy(1)-Au(1) bond length is 1.86 Å. In the second Dy site, Dy(2) is bonded in a distorted linear geometry to one Yb(1) and one Au(1) atom. The Dy(2)-Au(1) bond length is 1.86 Å. Au(1) is bonded in a distorted linear geometry to three equivalent Yb(1), one Dy(1), and one Dy(2) atom.
