Dy2EuCd crystallizes in the trigonal R3m space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to one Eu(1) and three equivalent Cd(1) atoms to form distorted corner-sharing DyEuCd3 tetrahedra. The Dy(1)-Eu(1) bond length is 0.99 Å. All Dy(1)-Cd(1) bond lengths are 3.47 Å. In the second Dy site, Dy(2) is bonded in a distorted linear geometry to one Eu(1) and one Cd(1) atom. The Dy(2)-Eu(1) bond length is 0.99 Å. The Dy(2)-Cd(1) bond length is 0.99 Å. Eu(1) is bonded in a linear geometry to one Dy(1) and one Dy(2) atom. Cd(1) is bonded in a single-bond geometry to one Dy(2) and three equivalent Dy(1) atoms.
