(Zn)2Hg(Pb) crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Hg(Pb) cluster and one zinc molecule. In the Hg(Pb) cluster, Hg(1) is bonded in a distorted single-bond geometry to one Pb(1) atom. The Hg(1)-Pb(1) bond length is 1.21 Å. Pb(1) is bonded in a 1-coordinate geometry to one Hg(1) atom.
