W2TcSn crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two W2TcSn clusters. There are two inequivalent W sites. In the first W site, W(1) is bonded in a single-bond geometry to one W(2) and one Sn(1) atom. The W(1)-W(2) bond length is 1.82 Å. The W(1)-Sn(1) bond length is 1.18 Å. In the second W site, W(2) is bonded in a 2-coordinate geometry to one W(1) and one Tc(1) atom. The W(2)-Tc(1) bond length is 2.59 Å. Tc(1) is bonded in a 1-coordinate geometry to one W(2) atom. Sn(1) is bonded in a single-bond geometry to one W(1) atom.
