RhHg2Ga is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one RhHg2Ga cluster. Rh(1) is bonded in a single-bond geometry to one Hg(1) atom. The Rh(1)-Hg(1) bond length is 1.03 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a bent 150 degrees geometry to one Rh(1) and one Hg(2) atom. The Hg(1)-Hg(2) bond length is 0.28 Å. In the second Hg site, Hg(2) is bonded in a bent 150 degrees geometry to one Hg(1) and one Ga(1) atom. The Hg(2)-Ga(1) bond length is 0.79 Å. Ga(1) is bonded in a single-bond geometry to one Hg(2) atom.
