The material described by LiCeSn 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 one Ce(1), four equivalent Ce(2), 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 Ce(2), one Sn(2), and three equivalent Sn(1) atoms. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 9-coordinate geometry to three equivalent Li(1) and six equivalent Sn(1) atoms. In the second Ce site, Ce(2) 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. 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 Ce(1), and four equivalent Ce(2) 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 Ce(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
