Ce5Ga2Ge crystallizes in the tetragonal I4/mcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded to four equivalent Ga(1) and two equivalent Ge(1) atoms to form corner-sharing CeGa4Ge2 octahedra. The corner-sharing octahedral tilt angles range from 0-55°. In the second Ce site, Ce(2) is bonded in a 6-coordinate geometry to one Ce(2), three equivalent Ga(1), and two equivalent Ge(1) atoms. Ga(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), six equivalent Ce(2), and one Ga(1) atom. Ge(1) is bonded in a 10-coordinate geometry to two equivalent Ce(1) and eight equivalent Ce(2) atoms.

In the first Ce site, Ce(1) is bonded to four equivalent Ga(1) and two equivalent Ge(1) atoms to form corner-sharing CeGa4Ge2 octahedra. The corner-sharing octahedral tilt angles range from 0-55°. All Ce(1)-Ga(1) bond lengths are 3.19 Å. Both Ce(1)-Ge(1) bond lengths are 3.11 Å. In the second Ce site, Ce(2) is bonded in a 6-coordinate geometry to one Ce(2), three equivalent Ga(1), and two equivalent Ge(1) atoms. The Ce(2)-Ce(2) bond length is 2.80 Å. There is one shorter (3.05 Å) and two longer (3.13 Å) Ce(2)-Ga(1) bond lengths. Both Ce(2)-Ge(1) bond lengths are 3.16 Å. Ga(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), six equivalent Ce(2), and one Ga(1) atom. The Ga(1)-Ga(1) bond length is 2.74 Å. Ge(1) is bonded in a 10-coordinate geometry to two equivalent Ce(1) and eight equivalent Ce(2) atoms.
