Os2IrAg crystallizes in the triclinic P1 space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 2-coordinate geometry to one Os(2) and two equivalent Ag(1) atoms. The Os(1)-Os(2) bond length is 3.61 Å. There is one shorter (1.81 Å) and one longer (2.28 Å) Os(1)-Ag(1) bond length. In the second Os site, Os(2) is bonded in a 9-coordinate geometry to one Os(1), six equivalent Os(2), and two equivalent Ir(1) atoms. There are four shorter (2.71 Å) and two longer (2.74 Å) Os(2)-Os(2) bond lengths. There is one shorter (3.20 Å) and one longer (3.49 Å) Os(2)-Ir(1) bond length. Ir(1) is bonded in a single-bond geometry to two equivalent Os(2) and one Ag(1) atom. The Ir(1)-Ag(1) bond length is 1.53 Å. Ag(1) is bonded in a 3-coordinate geometry to two equivalent Os(1) and one Ir(1) atom.
