Hg Ir Au Au
IrAu2Hg is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two IrAu2Hg clusters. Ir(1) is bonded in a single-bond geometry to one Au(2) atom. The Ir(1)-Au(2) bond length is 1.48 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a single-bond geometry to one Hg(1) atom. The Au(1)-Hg(1) bond length is 0.81 Å. In the second Au site, Au(2) is bonded in a distorted single-bond geometry to one Ir(1) and one Hg(1) atom. The Au(2)-Hg(1) bond length is 0.16 Å. Hg(1) is bonded in a linear geometry to one Au(1) and one Au(2) atom.
