Nd2Sb crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded to five equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing NdSb5 trigonal bipyramids. In the second Nd site, Nd(2) is bonded in a 4-coordinate geometry to four equivalent Sb(1) atoms. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Nd(2) and five equivalent Nd(1) atoms.

In the first Nd site, Nd(1) is bonded to five equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing NdSb5 trigonal bipyramids. There is one shorter (3.25 Å) and four longer (3.31 Å) Nd(1)-Sb(1) bond lengths. In the second Nd site, Nd(2) is bonded in a 4-coordinate geometry to four equivalent Sb(1) atoms. All Nd(2)-Sb(1) bond lengths are 3.36 Å. Sb(1) is bonded in a 9-coordinate geometry to four equivalent Nd(2) and five equivalent Nd(1) atoms.
