Mo Mo Os Pb
Mo2OsPb crystallizes in the triclinic P1 space group. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a single-bond geometry to one Os(1) and two equivalent Pb(1) atoms. The Mo(1)-Os(1) bond length is 0.12 Å. There is one shorter (2.85 Å) and one longer (3.47 Å) Mo(1)-Pb(1) bond length. In the second Mo site, Mo(2) is bonded in a distorted single-bond geometry to one Os(1) and two equivalent Pb(1) atoms. The Mo(2)-Os(1) bond length is 1.50 Å. There is one shorter (2.83 Å) and one longer (3.10 Å) Mo(2)-Pb(1) bond length. Os(1) is bonded in a distorted single-bond geometry to one Mo(1) and one Mo(2) atom. Pb(1) is bonded in a 6-coordinate geometry to two equivalent Mo(1), two equivalent Mo(2), and two equivalent Pb(1) atoms. Both Pb(1)-Pb(1) bond lengths are 3.06 Å.
