The structure described by ThCo2Sn2 crystallizes in the tetragonal P4/nmm space group. Th(1) is bonded in a 16-coordinate geometry to four equivalent Co(1), four equivalent Co(2), four equivalent Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 8-coordinate geometry to four equivalent Th(1) and four equivalent Sn(2) atoms. In the second Co site, Co(2) is bonded in a 5-coordinate geometry to four equivalent Th(1), one Sn(2), and four equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 4-coordinate geometry to four equivalent Th(1) and four equivalent Co(2) atoms. In the second Sn site, Sn(2) is bonded in a 5-coordinate geometry to four equivalent Th(1), one Co(2), and four equivalent Co(1) atoms. is represented by the CIF file [CIF]
