AgHgZn2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AgHgZn2 cluster. Ag(1) is bonded in a single-bond geometry to one Zn(1) and one Zn(2) atom. The Ag(1)-Zn(1) bond length is 0.75 Å. The Ag(1)-Zn(2) bond length is 1.85 Å. Hg(1) is bonded in a distorted single-bond geometry to one Zn(2) atom. The Hg(1)-Zn(2) bond length is 2.18 Å. There are two inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a single-bond geometry to one Ag(1) atom. In the second Zn site, Zn(2) is bonded in a 2-coordinate geometry to one Ag(1) and one Hg(1) atom.
