The structure described by Tm3Ir3Ga8 crystallizes in the orthorhombic Immm space group. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded to four equivalent Ga(1) and eight equivalent Ga(2) atoms to form distorted face-sharing TmGa12 cuboctahedra. In the second Tm site, Tm(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 8-coordinate geometry to four equivalent Tm(2) and four equivalent Ga(1) atoms. In the second Ir site, Ir(2) is bonded in a 8-coordinate geometry to two equivalent Tm(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 Tm(1), two equivalent Tm(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 Tm(1), two equivalent Tm(2), one Ir(2), one Ga(2), and three equivalent Ga(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
