The compound described by Ce5Sn3 crystallizes in the orthorhombic Cmcm space group. There are three inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 6-coordinate geometry to two equivalent Sn(1) and four equivalent Sn(2) atoms. In the second Ce site, Ce(2) is bonded in a 5-coordinate geometry to two equivalent Sn(2) and three equivalent Sn(1) atoms. In the third Ce site, Ce(3) is bonded in a 5-coordinate geometry to one Sn(1) and four equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to two equivalent Ce(3), three equivalent Ce(2), and four equivalent Ce(1) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to one Ce(2), four equivalent Ce(1), and four equivalent Ce(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
