Yb is alpha La structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded to six equivalent Yb(1) and six equivalent Yb(2) atoms to form a mixture of corner, face, and edge-sharing YbYb12 cuboctahedra. In the second Yb site, Yb(2) is bonded to six equivalent Yb(1) and six equivalent Yb(2) atoms to form a mixture of corner, face, and edge-sharing YbYb12 cuboctahedra.

In the first Yb site, Yb(1) is bonded to six equivalent Yb(1) and six equivalent Yb(2) atoms to form a mixture of corner, face, and edge-sharing YbYb12 cuboctahedra. All Yb(1)-Yb(1) bond lengths are 3.81 Å. All Yb(1)-Yb(2) bond lengths are 3.85 Å. In the second Yb site, Yb(2) is bonded to six equivalent Yb(1) and six equivalent Yb(2) atoms to form a mixture of corner, face, and edge-sharing YbYb12 cuboctahedra. All Yb(2)-Yb(2) bond lengths are 3.81 Å.
