Cr Ir Os Os
CrOs2Ir crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CrOs2Ir cluster. Cr(1) is bonded in a 2-coordinate geometry to one Os(1) and one Ir(1) atom. The Cr(1)-Os(1) bond length is 1.80 Å. The Cr(1)-Ir(1) bond length is 1.42 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 2-coordinate geometry to one Cr(1) and one Os(2) atom. The Os(1)-Os(2) bond length is 0.89 Å. In the second Os site, Os(2) is bonded in a single-bond geometry to one Os(1) atom. Ir(1) is bonded in a distorted single-bond geometry to one Cr(1) atom.
