The material described by Tm3Rh3Ga8 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 Rh(1), two equivalent Rh(2), four equivalent Ga(1), and four equivalent Ga(2) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a distorted body-centered cubic geometry to four equivalent Tm(2) and four equivalent Ga(1) atoms. In the second Rh site, Rh(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 Rh(1), two equivalent Rh(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 Rh(2), one Ga(2), and three equivalent Ga(1) atoms. is represented by the CIF file [CIF]
