The crystal structure described by TmGa6 crystallizes in the tetragonal P4/nbm space group. Tm(1) is bonded to four equivalent Ga(2) and eight equivalent Ga(1) atoms to form a mixture of edge and face-sharing TmGa12 cuboctahedra. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 9-coordinate geometry to four equivalent Tm(1), one Ga(1), and four equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 4-coordinate geometry to one Tm(1), one Ga(2), and two equivalent Ga(1) atoms. is represented by the CIF file [CIF]
