Os2PbBi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Os2PbBi clusters. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 1-coordinate geometry to one Pb(1) and one Bi(1) atom. The Os(1)-Pb(1) bond length is 1.63 Å. The Os(1)-Bi(1) bond length is 2.28 Å. In the second Os site, Os(2) is bonded in a distorted single-bond geometry to one Bi(1) atom. The Os(2)-Bi(1) bond length is 2.28 Å. Pb(1) is bonded in a distorted single-bond geometry to one Os(1) and one Bi(1) atom. The Pb(1)-Bi(1) bond length is 2.48 Å. Bi(1) is bonded in a 3-coordinate geometry to one Os(1), one Os(2), and one Pb(1) atom.
