W2Tl is Hg_xSn structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one W2Tl cluster. There are four inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to one W(2) and one Tl(2) atom. The W(1)-W(2) bond length is 1.15 Å. The W(1)-Tl(2) bond length is 2.81 Å. In the second W site, W(2) is bonded in a 1-coordinate geometry to one W(1) and one Tl(1) atom. The W(2)-Tl(1) bond length is 1.66 Å. In the third W site, W(3) is bonded in a single-bond geometry to one Tl(2) atom. The W(3)-Tl(2) bond length is 1.15 Å. In the fourth W site, W(4) is bonded in a single-bond geometry to one Tl(1) atom. The W(4)-Tl(1) bond length is 1.15 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 2-coordinate geometry to one W(2) and one W(4) atom. In the second Tl site, Tl(2) is bonded in a single-bond geometry to one W(1) and one W(3) atom.
