Lu3Ir4Ge13 crystallizes in the cubic Pm-3n space group. Lu(1) is bonded in a 16-coordinate geometry to four equivalent Ir(1) and twelve equivalent Ge(2) atoms. Ir(1) is bonded in a 9-coordinate geometry to three equivalent Lu(1) and six equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 6-coordinate geometry to three equivalent Lu(1), two equivalent Ir(1), one Ge(1), and one Ge(2) atom. In the second Ge site, Ge(1) is bonded in a cuboctahedral geometry to twelve equivalent Ge(2) atoms.
