The compound described by LaRhSn2 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 14-coordinate geometry to four equivalent Rh(1), two equivalent Sn(3), four equivalent Sn(1), and four equivalent Sn(2) atoms. In the second La site, La(2) is bonded in a 15-coordinate geometry to six equivalent Rh(1), one Sn(1), two equivalent Sn(2), and six equivalent Sn(3) atoms. Rh(1) is bonded in a 10-coordinate geometry to two equivalent La(1), three equivalent La(2), one Sn(1), one Sn(2), and three equivalent Sn(3) atoms. There are three inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 2-coordinate geometry to one La(2), four equivalent La(1), two equivalent Rh(1), and one Sn(2) atom. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent La(2), four equivalent La(1), two equivalent Rh(1), and one Sn(1) atom. In the third Sn site, Sn(3) is bonded in a 3-coordinate geometry to one La(1), three equivalent La(2), and three equivalent Rh(1) atoms. is represented by the CIF card [CIF]
