Sc Hg Pb
ScHgPb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScHgPb clusters. Sc(1) is bonded in a single-bond geometry to one Hg(1) atom. The Sc(1)-Hg(1) bond length is 1.97 Å. Hg(1) is bonded in a bent 150 degrees geometry to one Sc(1) and one Pb(1) atom. The Hg(1)-Pb(1) bond length is 1.87 Å. Pb(1) is bonded in a single-bond geometry to one Hg(1) atom.
