Lu3Ir2Ge3 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 11-coordinate geometry to four equivalent Ir(1), two equivalent Ge(2), and five equivalent Ge(1) atoms. In the second Lu site, Lu(2) is bonded in a 9-coordinate geometry to four equivalent Ir(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. Ir(1) is bonded in a 10-coordinate geometry to two equivalent Lu(2), four equivalent Lu(1), one Ge(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to one Lu(2), five equivalent Lu(1), three equivalent Ir(1), and one Ge(1) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Lu(2), four equivalent Lu(1), and two equivalent Ir(1) atoms.

In the first Lu site, Lu(1) is bonded in a 11-coordinate geometry to four equivalent Ir(1), two equivalent Ge(2), and five equivalent Ge(1) atoms. There are a spread of Lu(1)-Ir(1) bond distances ranging from 2.90-3.21 Å. Both Lu(1)-Ge(2) bond lengths are 2.97 Å. There are two shorter (2.97 Å) and three longer (3.17 Å) Lu(1)-Ge(1) bond lengths. In the second Lu site, Lu(2) is bonded in a 9-coordinate geometry to four equivalent Ir(1), two equivalent Ge(1), and three equivalent Ge(2) atoms. All Lu(2)-Ir(1) bond lengths are 3.01 Å. Both Lu(2)-Ge(1) bond lengths are 3.02 Å. There are two shorter (2.97 Å) and one longer (3.02 Å) Lu(2)-Ge(2) bond length. Ir(1) is bonded in a 10-coordinate geometry to two equivalent Lu(2), four equivalent Lu(1), one Ge(2), and three equivalent Ge(1) atoms. The Ir(1)-Ge(2) bond length is 2.55 Å.
