LiGdSn crystallizes in the hexagonal P6_3mc space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 3-coordinate geometry to two equivalent Gd(2), four equivalent Gd(1), one Sn(2), and three equivalent Sn(1) atoms. In the second Li site, Li(2) is bonded in a 4-coordinate geometry to six equivalent Gd(1), one Sn(2), and three equivalent Sn(1) atoms. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 12-coordinate geometry to two equivalent Li(2), four equivalent Li(1), two equivalent Sn(2), and four equivalent Sn(1) atoms. In the second Gd site, Gd(2) is bonded in a 12-coordinate geometry to six equivalent Li(1) and six equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 10-coordinate geometry to one Li(2), three equivalent Li(1), two equivalent Gd(2), and four equivalent Gd(1) atoms. In the second Sn site, Sn(2) is bonded in a 10-coordinate geometry to one Li(2), three equivalent Li(1), and six equivalent Gd(1) atoms.

In the first Li site, Li(1) is bonded in a 3-coordinate geometry to two equivalent Gd(2), four equivalent Gd(1), one Sn(2), and three equivalent Sn(1) atoms. There is one shorter (3.16 Å) and one longer (3.48 Å) Li(1)-Gd(2) bond length. There are two shorter (3.23 Å) and two longer (3.42 Å) Li(1)-Gd(1) bond lengths. The Li(1)-Sn(2) bond length is 2.72 Å. There are two shorter (2.77 Å) and one longer (3.26 Å) Li(1)-Sn(1) bond length. In the second Li site, Li(2) is bonded in a 4-coordinate geometry to six equivalent Gd(1), one Sn(2), and three equivalent Sn(1) atoms. There are three shorter (3.21 Å) and three longer (3.52 Å) Li(2)-Gd(1) bond lengths. The Li(2)-Sn(2) bond length is 2.95 Å. All Li(2)-Sn(1) bond lengths are 2.77 Å.
