In In Hg Rh
RhHgIn2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RhHgIn2 clusters. Rh(1) is bonded in a 3-coordinate geometry to one Hg(1) and two equivalent In(1) atoms. The Rh(1)-Hg(1) bond length is 1.02 Å. Both Rh(1)-In(1) bond lengths are 0.74 Å. Hg(1) is bonded in a distorted single-bond geometry to one Rh(1) atom. In(1) is bonded in a single-bond geometry to one Rh(1) atom.
