The structure described by TaSn2 is Khatyrkite-like structured and crystallizes in the orthorhombic Fddd space group. Ta(1) is bonded in a 10-coordinate geometry to two equivalent Ta(1), four equivalent Sn(1), and four equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 4-coordinate geometry to four equivalent Ta(1) atoms. In the second Sn site, Sn(2) is bonded in a 4-coordinate geometry to four equivalent Ta(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
