Gd is alpha La structured and crystallizes in the trigonal P-3m1 space group. There are four inequivalent Gd sites. In the first Gd site, Gd(1) is bonded to six equivalent Gd(1) and six Gd(3,3) atoms to form a mixture of face, corner, and edge-sharing GdGd12 cuboctahedra. In the second Gd site, Gd(2) is bonded to six equivalent Gd(2) and six Gd(3,3) atoms to form a mixture of face, corner, and edge-sharing GdGd12 cuboctahedra. In the third Gd site, Gd(3) is bonded to three equivalent Gd(1), three equivalent Gd(2), and six equivalent Gd(3) atoms to form a mixture of face, corner, and edge-sharing GdGd12 cuboctahedra. In the fourth Gd site, Gd(3) is bonded to three equivalent Gd(1), three equivalent Gd(2), and six equivalent Gd(3) atoms to form a mixture of face, corner, and edge-sharing GdGd12 cuboctahedra.

In the first Gd site, Gd(1) is bonded to six equivalent Gd(1) and six Gd(3,3) atoms to form a mixture of face, corner, and edge-sharing GdGd12 cuboctahedra. All Gd(1)-Gd(1) bond lengths are 3.66 Å. All Gd(1)-Gd(3,3) bond lengths are 3.60 Å. In the second Gd site, Gd(2) is bonded to six equivalent Gd(2) and six Gd(3,3) atoms to form a mixture of face, corner, and edge-sharing GdGd12 cuboctahedra. All Gd(2)-Gd(2) bond lengths are 3.66 Å. All Gd(2)-Gd(3,3) bond lengths are 3.64 Å. In the third Gd site, Gd(3) is bonded to three equivalent Gd(1), three equivalent Gd(2), and six equivalent Gd(3) atoms to form a mixture of face, corner, and edge-sharing GdGd12 cuboctahedra.
