Lu5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. In the second Lu site, Lu(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 Lu(1) and five equivalent Lu(2) atoms.
Lu5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 6-coordinate geometry to six equivalent Ge(1) atoms. All Lu(1)-Ge(1) bond lengths are 2.97 Å. In the second Lu site, Lu(2) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. There are a spread of Lu(2)-Ge(1) bond distances ranging from 2.83-3.35 Å. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Lu(1) and five equivalent Lu(2) atoms.
