Ga Ag Ag Hg
Ag2HgGa is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Ag2HgGa clusters. There are two inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a single-bond geometry to one Ga(1) atom. The Ag(1)-Ga(1) bond length is 1.17 Å. In the second Ag site, Ag(2) is bonded in a single-bond geometry to one Hg(1) atom. The Ag(2)-Hg(1) bond length is 0.12 Å. Hg(1) is bonded in a distorted single-bond geometry to one Ag(2) and one Ga(1) atom. The Hg(1)-Ga(1) bond length is 2.14 Å. Ga(1) is bonded in a bent 150 degrees geometry to one Ag(1) and one Hg(1) atom.
