The compound described by Lu3Ir3Ga8 crystallizes in the orthorhombic Immm space group. There are two inequivalent Lu sites. In the first Lu site, Lu(1) is bonded in a 16-coordinate geometry to four equivalent Ir(2), four equivalent Ga(1), and eight equivalent Ga(2) atoms. In the second Lu site, Lu(2) is bonded in a 12-coordinate geometry to two equivalent Ir(1), two equivalent Ir(2), four equivalent Ga(1), and four equivalent Ga(2) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a distorted body-centered cubic geometry to four equivalent Lu(2) and four equivalent Ga(1) atoms. In the second Ir site, Ir(2) is bonded in a 8-coordinate geometry to two equivalent Lu(1), two equivalent Lu(2), two equivalent Ga(2), and four equivalent Ga(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to one Lu(1), two equivalent Lu(2), one Ir(1), two equivalent Ir(2), and three equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to two equivalent Lu(1), two equivalent Lu(2), one Ir(2), one Ga(2), and three equivalent Ga(1) atoms. is represented by the CIF file [CIF]
