Ir Os Pd Pd
OsIrPd2 crystallizes in the triclinic P1 space group. Os(1) is bonded in a 9-coordinate geometry to six equivalent Os(1), two equivalent Ir(1), and one Pd(2) atom. There are four shorter (2.72 Å) and two longer (2.74 Å) Os(1)-Os(1) bond lengths. There is one shorter (2.63 Å) and one longer (2.97 Å) Os(1)-Ir(1) bond length. The Os(1)-Pd(2) bond length is 3.20 Å. Ir(1) is bonded in a 9-coordinate geometry to two equivalent Os(1), six equivalent Ir(1), and one Pd(1) atom. There are four shorter (2.72 Å) and two longer (2.74 Å) Ir(1)-Ir(1) bond lengths. The Ir(1)-Pd(1) bond length is 3.48 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 2-coordinate geometry to one Ir(1) and two equivalent Pd(2) atoms. There is one shorter (1.07 Å) and one longer (1.75 Å) Pd(1)-Pd(2) bond length. In the second Pd site, Pd(2) is bonded in a 2-coordinate geometry to one Os(1) and two equivalent Pd(1) atoms.
