The material structure described by Tm5Ga3 crystallizes in the monoclinic C2/m space group. There are four inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 6-coordinate geometry to two equivalent Ga(1) and four equivalent Ga(2) atoms. In the second Tm site, Tm(2) is bonded in a 6-coordinate geometry to two equivalent Ga(1) and four equivalent Ga(2) atoms. In the third Tm site, Tm(3) is bonded in a 4-coordinate geometry to one Ga(1) and three equivalent Ga(2) atoms. In the fourth Tm site, Tm(4) is bonded in a 4-coordinate geometry to two equivalent Ga(1) and two equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to two equivalent Tm(1), two equivalent Tm(2), two equivalent Tm(3), two equivalent Tm(4), and one Ga(1) atom. In the second Ga site, Ga(2) is bonded in a 8-coordinate geometry to one Tm(4), two equivalent Tm(1), two equivalent Tm(2), and three equivalent Tm(3) atoms. is represented by the CIF file [CIF]
