Ce5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. In the second Ce site, Ce(2) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1) and five equivalent Ce(2) atoms.
Ce5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. All Ce(1)-Ge(1) bond lengths are 3.19 Å. In the second Ce site, Ce(2) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. There are a spread of Ce(2)-Ge(1) bond distances ranging from 3.00-3.27 Å. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ce(1) and five equivalent Ce(2) atoms.
