Lu6Co2Sn 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 Sn(1), and one Sn(2) atom. In the second Lu site, Lu(2) is bonded in a 4-coordinate geometry to one Co(1), two equivalent Co(2), one Sn(1), and one Sn(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 Sn(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 Lu(1), two equivalent Lu(2), and four equivalent Lu(3) atoms. 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 Sn sites. In the first Sn site, Sn(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 Sn site, Sn(2) is bonded in a distorted body-centered cubic geometry to four equivalent Lu(1) and four equivalent Lu(2) atoms.
