PtHgIn2 is Cyanogen Chloride-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one PtHgIn2 cluster. Pt(1) is bonded in a single-bond geometry to one Hg(1) atom. The Pt(1)-Hg(1) bond length is 0.65 Å. Hg(1) is bonded in a linear geometry to one Pt(1) and one In(1) atom. The Hg(1)-In(1) bond length is 1.13 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a linear geometry to one Hg(1) and one In(2) atom. The In(1)-In(2) bond length is 0.59 Å. In the second In site, In(2) is bonded in a single-bond geometry to one In(1) atom.
