Lu6Co2In crystallizes in the orthorhombic Immm space group. There are three inequivalent Lu sites. In the first Lu site, Lu(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 Lu site, Lu(2) is bonded in a 5-coordinate geometry to one Co(1), two equivalent Co(2), one In(1), and one In(2) atom. In the third Lu site, Lu(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 9-coordinate geometry to two equivalent Lu(1), two equivalent Lu(2), four equivalent Lu(3), and one Co(1) atom. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Lu(1), two equivalent Lu(3), four equivalent Lu(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 Lu(1), four equivalent Lu(2), and four equivalent Lu(3) atoms. In the second In site, In(2) is bonded in a body-centered cubic geometry to four equivalent Lu(1) and four equivalent Lu(2) atoms.
