IrAgCu2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one IrAgCu2 cluster. Ir(1) is bonded in a distorted single-bond geometry to one Ag(1) and one Cu(1) atom. The Ir(1)-Ag(1) bond length is 0.97 Å. The Ir(1)-Cu(1) bond length is 1.97 Å. Ag(1) is bonded in a 1-coordinate geometry to one Ir(1) and one Cu(2) atom. The Ag(1)-Cu(2) bond length is 1.26 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 1-coordinate geometry to one Ir(1) atom. In the second Cu site, Cu(2) is bonded in a 1-coordinate geometry to one Ag(1) atom.
