The material structure described by Tm6Co2Sn crystallizes in the orthorhombic Immm space group. There are three inequivalent Tm sites. In the first Tm site, Tm(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 Tm site, Tm(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 Tm site, Tm(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 Tm(1), two equivalent Tm(2), and four equivalent Tm(3) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Tm(1), two equivalent Tm(3), four equivalent Tm(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 Tm(1), four equivalent Tm(2), and four equivalent Tm(3) atoms. In the second Sn site, Sn(2) is bonded in a distorted body-centered cubic geometry to four equivalent Tm(1) and four equivalent Tm(2) atoms. is represented by the CIF card [CIF]
