V Ir Os Os
VOs2Ir crystallizes in the triclinic P1 space group. V(1) is bonded in a 2-coordinate geometry to two equivalent Os(1) and two equivalent Os(2) atoms. There is one shorter (2.09 Å) and one longer (2.36 Å) V(1)-Os(1) bond length. There is one shorter (1.39 Å) and one longer (1.77 Å) V(1)-Os(2) bond length. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 2-coordinate geometry to two equivalent V(1) and one Ir(1) atom. The Os(1)-Ir(1) bond length is 3.35 Å. In the second Os site, Os(2) is bonded in a distorted bent 120 degrees geometry to two equivalent V(1) and one Ir(1) atom. The Os(2)-Ir(1) bond length is 3.35 Å. Ir(1) is bonded in a 8-coordinate geometry to one Os(1), one Os(2), and six equivalent Ir(1) atoms. There are four shorter (2.70 Å) and two longer (2.83 Å) Ir(1)-Ir(1) bond lengths.
