VHg2Sn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one VHg2Sn cluster. V(1) is bonded in a single-bond geometry to one Hg(2) atom. The V(1)-Hg(2) bond length is 1.20 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a single-bond geometry to one Sn(1) atom. The Hg(1)-Sn(1) bond length is 0.74 Å. In the second Hg site, Hg(2) is bonded in a 2-coordinate geometry to one V(1) and one Sn(1) atom. The Hg(2)-Sn(1) bond length is 1.35 Å. Sn(1) is bonded in a 2-coordinate geometry to one Hg(1) and one Hg(2) atom.
