Os2IrGe crystallizes in the monoclinic Cm space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a single-bond geometry to one Os(2) and one Ge(1) atom. The Os(1)-Os(2) bond length is 3.24 Å. The Os(1)-Ge(1) bond length is 0.65 Å. In the second Os site, Os(2) is bonded to one Os(1), six equivalent Os(2), and one Ir(1) atom to form a mixture of distorted edge and corner-sharing OsIrOs7 hexagonal bipyramids. All Os(2)-Os(2) bond lengths are 2.81 Å. The Os(2)-Ir(1) bond length is 2.71 Å. Ir(1) is bonded in a single-bond geometry to one Os(2) and one Ge(1) atom. The Ir(1)-Ge(1) bond length is 2.06 Å. Ge(1) is bonded in a single-bond geometry to one Os(1) and one Ir(1) atom.
