La5FeGe3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 7-coordinate geometry to two equivalent Fe(1) and five equivalent Ge(1) atoms. In the second La site, La(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. Fe(1) is bonded to six equivalent La(1) atoms to form face-sharing FeLa6 octahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent La(2) and five equivalent La(1) atoms.

In the first La site, La(1) is bonded in a 7-coordinate geometry to two equivalent Fe(1) and five equivalent Ge(1) atoms. Both La(1)-Fe(1) bond lengths are 2.87 Å. There are a spread of La(1)-Ge(1) bond distances ranging from 3.18-3.76 Å. In the second La site, La(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. All La(2)-Ge(1) bond lengths are 3.31 Å. Fe(1) is bonded to six equivalent La(1) atoms to form face-sharing FeLa6 octahedra. Ge(1) is bonded in a 9-coordinate geometry to four equivalent La(2) and five equivalent La(1) atoms.
