Cu Cu Ir Rh
IrRhCu2 is Indium-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two IrRhCu2 clusters. Ir(1) is bonded in a 2-coordinate geometry to two equivalent Cu(1) atoms. Both Ir(1)-Cu(1) bond lengths are 1.07 Å. Rh(1) is bonded in a 2-coordinate geometry to two equivalent Cu(1) atoms. Both Rh(1)-Cu(1) bond lengths are 0.54 Å. Cu(1) is bonded in a 3-coordinate geometry to one Ir(1), one Rh(1), and one Cu(1) atom. The Cu(1)-Cu(1) bond length is 0.54 Å.
