Tl Tl Os Pb
OsTl2Pb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two OsTl2Pb clusters. Os(1) is bonded in a distorted single-bond geometry to one Tl(1) and one Pb(1) atom. The Os(1)-Tl(1) bond length is 1.68 Å. The Os(1)-Pb(1) bond length is 2.65 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a distorted single-bond geometry to one Os(1) and one Tl(2) atom. The Tl(1)-Tl(2) bond length is 2.10 Å. In the second Tl site, Tl(2) is bonded in a distorted single-bond geometry to one Tl(1) atom. Pb(1) is bonded in a distorted single-bond geometry to one Os(1) atom.
