The crystal structure described by Ce5AgSn3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 7-coordinate geometry to two equivalent Ag(1) and five equivalent Sn(1) atoms. In the second Ce site, Ce(2) is bonded in a 6-coordinate geometry to six equivalent Sn(1) atoms. Ag(1) is bonded to six equivalent Ce(1) atoms to form distorted face-sharing AgCe6 octahedra. Sn(1) is bonded in a 9-coordinate geometry to four equivalent Ce(2) and five equivalent Ce(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
