The material structure described by CoSn2 is Khatyrkite structured and crystallizes in the tetragonal I4/mcm space group. Co(1) is bonded in a 10-coordinate geometry to two equivalent Co(1) and eight equivalent Sn(1) atoms. Sn(1) is bonded in a 4-coordinate geometry to four equivalent Co(1) atoms. is represented by the CIF file [CIF]
