The structure described by CeRhSn2 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 15-coordinate geometry to six equivalent Rh(1), one Sn(2), two equivalent Sn(3), and six equivalent Sn(1) atoms. In the second Ce site, Ce(2) is bonded in a 14-coordinate geometry to four equivalent Rh(1), two equivalent Sn(1), four equivalent Sn(2), and four equivalent Sn(3) atoms. Rh(1) is bonded in a 10-coordinate geometry to two equivalent Ce(2), three equivalent Ce(1), one Sn(2), one Sn(3), and three equivalent Sn(1) atoms. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 3-coordinate geometry to one Ce(2), three equivalent Ce(1), and three equivalent Rh(1) atoms. In the second Sn site, Sn(2) is bonded in a 2-coordinate geometry to one Ce(1), four equivalent Ce(2), two equivalent Rh(1), and one Sn(3) atom. In the third Sn site, Sn(3) is bonded in a 9-coordinate geometry to two equivalent Ce(1), four equivalent Ce(2), two equivalent Rh(1), and one Sn(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
