Dy is alpha Samarium structured and crystallizes in the trigonal R-3m space group. There are four inequivalent Dy sites. In the first Dy site, Dy(1) is bonded to six equivalent Dy(1) and six equivalent Dy(2) atoms to form a mixture of face, corner, and edge-sharing DyDy12 cuboctahedra. In the second Dy site, Dy(2) is bonded to three equivalent Dy(1) and nine equivalent Dy(2) atoms to form a mixture of face, corner, and edge-sharing DyDy12 cuboctahedra. In the third Dy site, Dy(2) is bonded to three equivalent Dy(1) and nine equivalent Dy(2) atoms to form a mixture of face, corner, and edge-sharing DyDy12 cuboctahedra. In the fourth Dy site, Dy(2) is bonded to three equivalent Dy(1) and nine Dy(2,2) atoms to form a mixture of face, corner, and edge-sharing DyDy12 cuboctahedra.

In the first Dy site, Dy(1) is bonded to six equivalent Dy(1) and six equivalent Dy(2) atoms to form a mixture of face, corner, and edge-sharing DyDy12 cuboctahedra. All Dy(1)-Dy(1) bond lengths are 3.59 Å. All Dy(1)-Dy(2) bond lengths are 3.52 Å. In the second Dy site, Dy(2) is bonded to three equivalent Dy(1) and nine equivalent Dy(2) atoms to form a mixture of face, corner, and edge-sharing DyDy12 cuboctahedra. There are three shorter (3.51 Å) and six longer (3.59 Å) Dy(2)-Dy(2) bond lengths. In the third Dy site, Dy(2) is bonded to three equivalent Dy(1) and nine equivalent Dy(2) atoms to form a mixture of face, corner, and edge-sharing DyDy12 cuboctahedra. All Dy(2)-Dy(1) bond lengths are 3.52 Å. There are three shorter (3.51 Å) and six longer (3.59 Å) Dy(2)-Dy(2) bond lengths. In the fourth Dy site, Dy(2) is bonded to three equivalent Dy(1) and nine Dy(2,2) atoms to form a mixture of face, corner, and edge-sharing DyDy12 cuboctahedra. All Dy(2)-Dy(1) bond lengths are 3.52 Å. There are three shorter (3.51 Å) and six longer (3.59 Å) Dy(2)-Dy(2,2) bond lengths.
