La5Ge3O 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 2-coordinate geometry to five equivalent Ge(1) and two equivalent O(1) atoms. In the second La site, La(2) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent La(2) and five equivalent La(1) atoms. O(1) is bonded to six equivalent La(1) atoms to form face-sharing OLa6 octahedra.
La5Ge3O 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 2-coordinate geometry to five equivalent Ge(1) and two equivalent O(1) atoms. There are a spread of La(1)-Ge(1) bond distances ranging from 3.11-3.69 Å. Both La(1)-O(1) bond lengths are 2.66 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 3.23 Å. Ge(1) is bonded in a 9-coordinate geometry to four equivalent La(2) and five equivalent La(1) atoms. O(1) is bonded to six equivalent La(1) atoms to form face-sharing OLa6 octahedra.
