The crystal structure described by Tb6Co2In 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 In(1), and one In(2) atom. In the second Tb site, Tb(2) is bonded in a 4-coordinate geometry to one Co(1), two equivalent Co(2), one In(1), and one In(2) atom. In the third Tb site, Tb(3) is bonded in a 4-coordinate geometry to one Co(2), two equivalent Co(1), and one In(1) 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(2), and four equivalent Tb(3) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Tb(1), two equivalent Tb(3), four equivalent Tb(2), and one Co(2) atom. There are two inequivalent In sites. In the first In site, In(1) is bonded in a cuboctahedral geometry to four equivalent Tb(1), four equivalent Tb(2), and four equivalent Tb(3) atoms. In the second In site, In(2) is bonded in a distorted body-centered cubic geometry to four equivalent Tb(1) and four equivalent Tb(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
