Sn Hg Rh Rh
Rh2HgSn crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Rh2HgSn cluster. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 2-coordinate geometry to one Hg(1) and one Sn(1) atom. The Rh(1)-Hg(1) bond length is 1.16 Å. The Rh(1)-Sn(1) bond length is 1.58 Å. In the second Rh site, Rh(2) is bonded in a 1-coordinate geometry to one Sn(1) atom. The Rh(2)-Sn(1) bond length is 1.85 Å. Hg(1) is bonded in a distorted single-bond geometry to one Rh(1) atom. Sn(1) is bonded in a 2-coordinate geometry to one Rh(1) and one Rh(2) atom.
