Cu Ni Ir Ir
Ir2NiCu crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ir2NiCu cluster. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 2-coordinate geometry to one Ni(1) and one Cu(1) atom. The Ir(1)-Ni(1) bond length is 1.26 Å. The Ir(1)-Cu(1) bond length is 1.50 Å. In the second Ir site, Ir(2) is bonded in a 2-coordinate geometry to one Ni(1) and one Cu(1) atom. The Ir(2)-Ni(1) bond length is 1.50 Å. The Ir(2)-Cu(1) bond length is 1.26 Å. Ni(1) is bonded in a 2-coordinate geometry to one Ir(1) and one Ir(2) atom. Cu(1) is bonded in a 2-coordinate geometry to one Ir(1) and one Ir(2) atom.
