As Ir Os Os
Os2IrAs crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Os2IrAs clusters. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a single-bond geometry to one Ir(1) atom. The Os(1)-Ir(1) bond length is 1.42 Å. In the second Os site, Os(2) is bonded in a distorted single-bond geometry to one Ir(1) and one As(1) atom. The Os(2)-Ir(1) bond length is 1.42 Å. The Os(2)-As(1) bond length is 2.42 Å. Ir(1) is bonded in a linear geometry to one Os(1) and one Os(2) atom. As(1) is bonded in a distorted single-bond geometry to one Os(2) atom.
