The structure 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 to two equivalent Sn(1) and four equivalent Sn(2) atoms to form distorted edge-sharing CeSn6 octahedra. In the second Ce site, Ce(2) is bonded in a 12-coordinate geometry to six equivalent Ag(1), two equivalent Sn(1), and four equivalent Sn(2) atoms. Ag(1) is bonded in a 8-coordinate geometry to three equivalent Ce(2), one Ag(1), one Sn(2), and three equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to one Ce(1), two equivalent Ce(2), and six equivalent Ag(1) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to two equivalent Ce(1), four equivalent Ce(2), two equivalent Ag(1), and one Sn(2) atom. is represented by the CIF card [CIF]
