Nd is alpha Samarium structured and crystallizes in the trigonal R-3m space group. There are five inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to six equivalent Nd(1) and six Nd(2,2) atoms to form a mixture of corner, edge, and face-sharing NdNd12 cuboctahedra. In the second Nd site, Nd(2) is bonded to three equivalent Nd(1) and nine Nd(2,2) atoms to form a mixture of corner, edge, and face-sharing NdNd12 cuboctahedra. In the third Nd site, Nd(2) is bonded to three equivalent Nd(1) and nine Nd(2,2) atoms to form a mixture of corner, edge, and face-sharing NdNd12 cuboctahedra. In the fourth Nd site, Nd(2) is bonded to three equivalent Nd(1) and nine Nd(2,2) atoms to form a mixture of corner, edge, and face-sharing NdNd12 cuboctahedra. In the fifth Nd site, Nd(2) is bonded to three equivalent Nd(1) and nine Nd(2,2) atoms to form a mixture of corner, edge, and face-sharing NdNd12 cuboctahedra.

In the first Nd site, Nd(1) is bonded to six equivalent Nd(1) and six Nd(2,2) atoms to form a mixture of corner, edge, and face-sharing NdNd12 cuboctahedra. All Nd(1)-Nd(1) bond lengths are 3.73 Å. All Nd(1)-Nd(2,2) bond lengths are 3.66 Å. In the second Nd site, Nd(2) is bonded to three equivalent Nd(1) and nine Nd(2,2) atoms to form a mixture of corner, edge, and face-sharing NdNd12 cuboctahedra. There are three shorter (3.68 Å) and six longer (3.73 Å) Nd(2)-Nd(2,2) bond lengths. In the third Nd site, Nd(2) is bonded to three equivalent Nd(1) and nine Nd(2,2) atoms to form a mixture of corner, edge, and face-sharing NdNd12 cuboctahedra. All Nd(2)-Nd(1) bond lengths are 3.66 Å. All Nd(2)-Nd(2) bond lengths are 3.73 Å.
