The material described by Tb3Ga2 crystallizes in the tetragonal I4/mcm space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 4-coordinate geometry to two equivalent Ga(3) and four equivalent Ga(4) atoms. In the second Tb site, Tb(2) is bonded in a 5-coordinate geometry to two equivalent Ga(4) and three equivalent Ga(3) atoms. In the third Tb site, Tb(3) is bonded in a 6-coordinate geometry to one Ga(1), one Ga(2), one Ga(3), and three equivalent Ga(4) atoms. There are four inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 8-coordinate geometry to eight equivalent Tb(3) atoms. In the second Ga site, Ga(2) is bonded in a body-centered cubic geometry to eight equivalent Tb(3) atoms. In the third Ga site, Ga(3) is bonded in a 9-coordinate geometry to two equivalent Tb(1), three equivalent Tb(2), and four equivalent Tb(3) atoms. In the fourth Ga site, Ga(4) is bonded in a 10-coordinate geometry to one Tb(2), two equivalent Tb(1), six equivalent Tb(3), and one Ga(4) atom. is represented by the CIF card [CIF]
