Ir Ir Ir Cl
Ir3Cl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Ir3Cl cluster. There are three inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a distorted single-bond geometry to one Cl(1) atom. The Ir(1)-Cl(1) bond length is 1.92 Å. In the second Ir site, Ir(2) is bonded in a distorted single-bond geometry to one Ir(3) atom. The Ir(2)-Ir(3) bond length is 0.92 Å. In the third Ir site, Ir(3) is bonded in a distorted bent 120 degrees geometry to one Ir(2) and one Cl(1) atom. The Ir(3)-Cl(1) bond length is 1.35 Å. Cl(1) is bonded in a distorted single-bond geometry to one Ir(1) and one Ir(3) atom.
