Ir Ir Os Pb
OsIr2Pb crystallizes in the triclinic P1 space group. Os(1) is bonded in a 2-coordinate geometry to one Ir(2) and two equivalent Pb(1) atoms. The Os(1)-Ir(2) bond length is 2.23 Å. There is one shorter (2.83 Å) and one longer (3.14 Å) Os(1)-Pb(1) bond length. There are two inequivalent Ir sites. In the first Ir site, Ir(1) is bonded in a 8-coordinate geometry to two equivalent Ir(2), four equivalent Ir(1), and two equivalent Pb(1) atoms. There is one shorter (2.39 Å) and one longer (2.76 Å) Ir(1)-Ir(2) bond length. All Ir(1)-Ir(1) bond lengths are 2.83 Å. There is one shorter (2.56 Å) and one longer (2.90 Å) Ir(1)-Pb(1) bond length. In the second Ir site, Ir(2) is bonded in a 2-coordinate geometry to one Os(1) and two equivalent Ir(1) atoms. Pb(1) is bonded in a 8-coordinate geometry to two equivalent Os(1), two equivalent Ir(1), and four equivalent Pb(1) atoms. All Pb(1)-Pb(1) bond lengths are 2.83 Å.
