Ce4Ge3 crystallizes in the trigonal R3 space group. There are four inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 4-coordinate geometry to one Ce(3) and three equivalent Ge(1) atoms. The Ce(1)-Ce(3) bond length is 1.92 Å. All Ce(1)-Ge(1) bond lengths are 2.53 Å. In the second Ce site, Ce(2) is bonded in a 3-coordinate geometry to one Ge(1) and two equivalent Ge(2) atoms. The Ce(2)-Ge(1) bond length is 2.25 Å. There is one shorter (2.66 Å) and one longer (2.78 Å) Ce(2)-Ge(2) bond length. In the third Ce site, Ce(3) is bonded in a single-bond geometry to one Ce(1) atom. In the fourth Ce site, Ce(4) is bonded in a distorted single-bond geometry to one Ge(1) and one Ge(2) atom. The Ce(4)-Ge(1) bond length is 1.48 Å. The Ce(4)-Ge(2) bond length is 2.36 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 1-coordinate geometry to one Ce(1), one Ce(2), and one Ce(4) atom. In the second Ge site, Ge(2) is bonded in a 3-coordinate geometry to one Ce(4) and two equivalent Ce(2) atoms.
