TaW2Sn is alpha Po structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one TaW2Sn cluster. Ta(1) is bonded in a 3-coordinate geometry to one W(1), one W(2), and one Sn(1) atom. The Ta(1)-W(1) bond length is 1.32 Å. The Ta(1)-W(2) bond length is 1.14 Å. The Ta(1)-Sn(1) bond length is 1.20 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to one Ta(1) and one Sn(1) atom. The W(1)-Sn(1) bond length is 1.14 Å. In the second W site, W(2) is bonded in a 2-coordinate geometry to one Ta(1) and one Sn(1) atom. The W(2)-Sn(1) bond length is 1.32 Å. Sn(1) is bonded in a 3-coordinate geometry to one Ta(1), one W(1), and one W(2) atom.
