The compound described by Ce3Ag4Sn4 crystallizes in the orthorhombic Immm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 8-coordinate geometry to six equivalent Ag(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. In the second Ce site, Ce(2) is bonded to eight equivalent Ag(1), two equivalent Sn(1), and two equivalent Sn(2) atoms to form distorted face-sharing CeAg8Sn4 cuboctahedra. Ag(1) is bonded in a 9-coordinate geometry to two equivalent Ce(2), three equivalent Ce(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 7-coordinate geometry to one Ce(2), two equivalent Ce(1), and four equivalent Ag(1) atoms. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to one Ce(2), two equivalent Ce(1), four equivalent Ag(1), and one Sn(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
