OsIrPd2 crystallizes in the triclinic P1 space group. Os(1) is bonded in a distorted single-bond geometry to two equivalent Ir(1) and one Pd(2) atom. There is one shorter (2.28 Å) and one longer (2.47 Å) Os(1)-Ir(1) bond length. The Os(1)-Pd(2) bond length is 1.47 Å. Ir(1) is bonded in a 6-coordinate geometry to two equivalent Os(1), two equivalent Ir(1), and two equivalent Pd(1) atoms. Both Ir(1)-Ir(1) bond lengths are 2.74 Å. There is one shorter (2.19 Å) and one longer (2.74 Å) Ir(1)-Pd(1) bond length. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 2-coordinate geometry to two equivalent Ir(1) and one Pd(2) atom. The Pd(1)-Pd(2) bond length is 2.25 Å. In the second Pd site, Pd(2) is bonded in a distorted single-bond geometry to one Os(1) and one Pd(1) atom.
