Li Li Hg Rh
Li2RhHg crystallizes in the monoclinic Cm space group. There are two inequivalent Li sites. In the first Li site, Li(1) is bonded in a 2-coordinate geometry to one Li(2) and one Hg(1) atom. The Li(1)-Li(2) bond length is 1.16 Å. The Li(1)-Hg(1) bond length is 2.85 Å. In the second Li site, Li(2) is bonded in a 5-coordinate geometry to one Li(1) and four equivalent Rh(1) atoms. There are a spread of Li(2)-Rh(1) bond distances ranging from 2.22-3.18 Å. Rh(1) is bonded in a 2-coordinate geometry to four equivalent Li(2) and one Hg(1) atom. The Rh(1)-Hg(1) bond length is 0.88 Å. Hg(1) is bonded in a single-bond geometry to one Li(1) and one Rh(1) atom.
