The structure described by Tb6Co2Ga crystallizes in the orthorhombic Immm space group. There are three inequivalent Tb sites. In the first Tb site, Tb(1) is bonded in a 4-coordinate geometry to one Co(1), one Co(2), one Ga(1), and one Ga(2) atom. In the second Tb site, Tb(2) is bonded in a 4-coordinate geometry to one Co(2), two equivalent Co(1), and one Ga(2) atom. In the third Tb site, Tb(3) is bonded in a 4-coordinate geometry to one Co(1), two equivalent Co(2), one Ga(1), and one Ga(2) atom. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 8-coordinate geometry to two equivalent Tb(1), two equivalent Tb(3), and four equivalent Tb(2) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Tb(1), two equivalent Tb(2), four equivalent Tb(3), and one Co(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 Tb(1) and four equivalent Tb(3) atoms. In the second Ga site, Ga(2) is bonded in a cuboctahedral geometry to four equivalent Tb(1), four equivalent Tb(2), and four equivalent Tb(3) atoms. is represented by the CIF card [CIF]
