The compound described by Ce3Cu4Ge4 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 Ge(1) and four equivalent Ge(2) atoms to form distorted edge-sharing CeGe6 octahedra. In the second Ce site, Ce(2) is bonded in a 12-coordinate geometry to six equivalent Cu(1), two equivalent Ge(1), and four equivalent Ge(2) atoms. Cu(1) is bonded in a 8-coordinate geometry to three equivalent Ce(2), one Cu(1), one Ge(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to one Ce(1), two equivalent Ce(2), and six equivalent Cu(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Ce(1), four equivalent Ce(2), two equivalent Cu(1), and one Ge(2) atom. is represented by the CIF file [CIF]
