Hg Mo Mo Pb
Mo2HgPb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one Mo2HgPb cluster. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a distorted single-bond geometry to one Pb(1) atom. The Mo(1)-Pb(1) bond length is 2.06 Å. In the second Mo site, Mo(2) is bonded in a distorted single-bond geometry to one Hg(1) atom. The Mo(2)-Hg(1) bond length is 2.06 Å. Hg(1) is bonded in a 2-coordinate geometry to one Mo(2) and one Pb(1) atom. The Hg(1)-Pb(1) bond length is 2.33 Å. Pb(1) is bonded in a 2-coordinate geometry to one Mo(1) and one Hg(1) atom.
