The crystal structure described by Ce3Ag4Ge4 crystallizes in the monoclinic C2/m space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 12-coordinate geometry to three equivalent Ag(1), three equivalent Ag(2), two equivalent Ge(2), and four equivalent Ge(1) atoms. In the second Ce site, Ce(2) is bonded to four equivalent Ag(1), four equivalent Ag(2), two equivalent Ge(2), and four equivalent Ge(1) atoms to form distorted face-sharing CeAg8Ge6 octahedra. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a 10-coordinate geometry to two equivalent Ce(2), three equivalent Ce(1), one Ag(2), one Ge(1), and three equivalent Ge(2) atoms. In the second Ag site, Ag(2) is bonded in a 10-coordinate geometry to two equivalent Ce(2), three equivalent Ce(1), one Ag(1), one Ge(1), and three equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Ce(2), four equivalent Ce(1), one Ag(1), one Ag(2), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Ce(2), two equivalent Ce(1), three equivalent Ag(1), and three equivalent Ag(2) atoms. is represented by the CIF file [CIF]
