Ir Ir Pd Pd
PdIr is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one PdIr cluster. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a distorted single-bond geometry to one Ir(2), one Pd(1), and one Pd(2) atom. The Ir(1)-Ir(2) bond length is 0.44 Å. The Ir(1)-Pd(1) bond length is 0.20 Å. The Ir(1)-Pd(2) bond length is 0.27 Å. In the second Ir site, Ir(2) is bonded in a 2-coordinate geometry to one Ir(1) and one Pd(2) atom. The Ir(2)-Pd(2) bond length is 0.44 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in an L-shaped geometry to one Ir(1) and one Pd(2) atom. The Pd(1)-Pd(2) bond length is 0.20 Å. In the second Pd site, Pd(2) is bonded in a distorted single-bond geometry to one Ir(1), one Ir(2), and one Pd(1) atom.
