Te Ir Os Os
Os2IrTe crystallizes in the triclinic P1 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), one Ir(1), and one Te(1) atom. The Os(1)-Os(2) bond length is 0.88 Å. The Os(1)-Ir(1) bond length is 2.31 Å. The Os(1)-Te(1) bond length is 2.82 Å. In the second Os site, Os(2) is bonded in a single-bond geometry to one Os(1), one Ir(1), and one Te(1) atom. The Os(2)-Ir(1) bond length is 2.31 Å. The Os(2)-Te(1) bond length is 2.90 Å. Ir(1) is bonded in a 4-coordinate geometry to one Os(1), one Os(2), and two equivalent Te(1) atoms. There is one shorter (2.52 Å) and one longer (2.57 Å) Ir(1)-Te(1) bond length. Te(1) is bonded in a 6-coordinate geometry to one Os(1), one Os(2), two equivalent Ir(1), and two equivalent Te(1) atoms. Both Te(1)-Te(1) bond lengths are 2.92 Å.
