LaAuHg2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two LaAuHg2 clusters. La(1) is bonded in a 3-coordinate geometry to one Au(1) and two equivalent Hg(1) atoms. The La(1)-Au(1) bond length is 1.71 Å. Both La(1)-Hg(1) bond lengths are 1.57 Å. Au(1) is bonded in a single-bond geometry to one La(1) atom. Hg(1) is bonded in a single-bond geometry to one La(1) atom.
