HgGa2Sn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one HgGa2Sn cluster. Hg(1) is bonded in a single-bond geometry to one Ga(1) atom. The Hg(1)-Ga(1) bond length is 1.62 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a linear geometry to one Hg(1) and one Ga(2) atom. The Ga(1)-Ga(2) bond length is 0.68 Å. In the second Ga site, Ga(2) is bonded in a linear geometry to one Ga(1) and one Sn(1) atom. The Ga(2)-Sn(1) bond length is 0.93 Å. Sn(1) is bonded in a single-bond geometry to one Ga(2) atom.
