V2Hg crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one V2Hg cluster. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 1-coordinate geometry to one V(2) atom. The V(1)-V(2) bond length is 2.44 Å. In the second V site, V(2) is bonded in a distorted single-bond geometry to one V(1) and one Hg(1) atom. The V(2)-Hg(1) bond length is 0.88 Å. Hg(1) is bonded in a distorted single-bond geometry to one V(2) atom.
