Gd2In crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded to six equivalent Gd(2) and five equivalent In(1) atoms to form a mixture of distorted face and corner-sharing GdGd6In5 trigonal bipyramids. In the second Gd site, Gd(2) is bonded in a 14-coordinate geometry to two equivalent Gd(2), six equivalent Gd(1), and six equivalent In(1) atoms. In(1) is bonded in a 11-coordinate geometry to five equivalent Gd(1) and six equivalent Gd(2) atoms.

In the first Gd site, Gd(1) is bonded to six equivalent Gd(2) and five equivalent In(1) atoms to form a mixture of distorted face and corner-sharing GdGd6In5 trigonal bipyramids. All Gd(1)-Gd(2) bond lengths are 3.57 Å. There are three shorter (3.14 Å) and two longer (3.38 Å) Gd(1)-In(1) bond lengths. In the second Gd site, Gd(2) is bonded in a 14-coordinate geometry to two equivalent Gd(2), six equivalent Gd(1), and six equivalent In(1) atoms. Both Gd(2)-Gd(2) bond lengths are 3.38 Å. All Gd(2)-In(1) bond lengths are 3.57 Å. In(1) is bonded in a 11-coordinate geometry to five equivalent Gd(1) and six equivalent Gd(2) atoms.
