Ir Ru Ru Au
(Ru)2AuIr is High Pressure Cadmuum Telluride structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one ruthenium molecule and one AuIr cluster. In the AuIr cluster, Ir(1) is bonded in a single-bond geometry to one Au(1) atom. The Ir(1)-Au(1) bond length is 1.09 Å. Au(1) is bonded in a single-bond geometry to one Ir(1) atom.
