Ir Pt Pt Rh
IrRhPt2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one IrRhPt2 cluster. Ir(1) is bonded in a 2-coordinate geometry to one Rh(1) and one Pt(2) atom. The Ir(1)-Rh(1) bond length is 2.08 Å. The Ir(1)-Pt(2) bond length is 1.95 Å. Rh(1) is bonded in a 2-coordinate geometry to one Ir(1) and one Pt(1) atom. The Rh(1)-Pt(1) bond length is 1.95 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 2-coordinate geometry to one Rh(1) and one Pt(2) atom. The Pt(1)-Pt(2) bond length is 2.08 Å. In the second Pt site, Pt(2) is bonded in a 1-coordinate geometry to one Ir(1) and one Pt(1) atom.
