VOsPb2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one VOsPb2 cluster. V(1) is bonded in a distorted single-bond geometry to one Pb(1) and one Pb(2) atom. The V(1)-Pb(1) bond length is 1.44 Å. The V(1)-Pb(2) bond length is 2.07 Å. Os(1) is bonded in a 1-coordinate geometry to one Pb(2) atom. The Os(1)-Pb(2) bond length is 1.44 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted single-bond geometry to one V(1) atom. In the second Pb site, Pb(2) is bonded in a 2-coordinate geometry to one V(1) and one Os(1) atom.
