The crystal structure described by CoSn crystallizes in the hexagonal P6/mmm space group. Co(1) is bonded in a 10-coordinate geometry to four equivalent Co(1), two equivalent 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 6-coordinate geometry to six equivalent Co(1) atoms. In the second Sn site, Sn(2) is bonded in a hexagonal planar geometry to six equivalent Co(1) atoms. is represented by the CIF file [CIF]
