Cr Ir Au Au
CrIrAu2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CrIrAu2 clusters. Cr(1) is bonded in a single-bond geometry to one Ir(1) and one Au(1) atom. The Cr(1)-Ir(1) bond length is 1.61 Å. The Cr(1)-Au(1) bond length is 0.17 Å. Ir(1) is bonded in a linear geometry to one Cr(1) and one Au(2) atom. The Ir(1)-Au(2) bond length is 1.78 Å. There are two inequivalent Au sites. In the first Au site, Au(1) is bonded in a single-bond geometry to one Cr(1) atom. In the second Au site, Au(2) is bonded in a single-bond geometry to one Ir(1) atom.
