Nd2In crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 14-coordinate geometry to two equivalent Nd(1), six equivalent Nd(2), and six equivalent In(1) atoms. In the second Nd site, Nd(2) is bonded to six equivalent Nd(1) and five equivalent In(1) atoms to form a mixture of corner and face-sharing NdNd6In5 trigonal bipyramids. In(1) is bonded in a 11-coordinate geometry to five equivalent Nd(2) and six equivalent Nd(1) atoms.
Nd2In crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 14-coordinate geometry to two equivalent Nd(1), six equivalent Nd(2), and six equivalent In(1) atoms. Both Nd(1)-Nd(1) bond lengths are 3.47 Å. All Nd(1)-Nd(2) bond lengths are 3.66 Å. All Nd(1)-In(1) bond lengths are 3.66 Å. In the second Nd site, Nd(2) is bonded to six equivalent Nd(1) and five equivalent In(1) atoms to form a mixture of corner and face-sharing NdNd6In5 trigonal bipyramids. There are three shorter (3.22 Å) and two longer (3.47 Å) Nd(2)-In(1) bond lengths. In(1) is bonded in a 11-coordinate geometry to five equivalent Nd(2) and six equivalent Nd(1) atoms.
