The structure described by Tm6Ni2Ga crystallizes in the orthorhombic Immm space group. There are three inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 4-coordinate geometry to one Ni(1), one Ni(2), one Ga(1), and one Ga(2) atom. In the second Tm site, Tm(2) is bonded in a 4-coordinate geometry to one Ni(2), two equivalent Ni(1), and one Ga(2) atom. In the third Tm site, Tm(3) is bonded in a 4-coordinate geometry to one Ni(1), two equivalent Ni(2), one Ga(1), and one Ga(2) atom. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 8-coordinate geometry to two equivalent Tm(1), two equivalent Tm(3), and four equivalent Tm(2) atoms. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to two equivalent Tm(1), two equivalent Tm(2), four equivalent Tm(3), and one Ni(2) atom. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a body-centered cubic geometry to four equivalent Tm(1) and four equivalent Tm(3) atoms. In the second Ga site, Ga(2) is bonded in a cuboctahedral geometry to four equivalent Tm(1), four equivalent Tm(2), and four equivalent Tm(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
