LiNdSn 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 distorted trigonal planar geometry to two equivalent Nd(2), four equivalent Nd(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 Nd(1), one Sn(2), and three equivalent Sn(1) atoms. There are two inequivalent Nd sites. In the first Nd site, Nd(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 Nd site, Nd(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 Nd(2), and four equivalent Nd(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 Nd(1) atoms.
