ScPb2Sb is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScPb2Sb clusters. Sc(1) is bonded in a single-bond geometry to one Pb(2) atom. The Sc(1)-Pb(2) bond length is 3.15 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a single-bond geometry to one Sb(1) atom. The Pb(1)-Sb(1) bond length is 1.33 Å. In the second Pb site, Pb(2) is bonded in a distorted single-bond geometry to one Sc(1) and one Sb(1) atom. The Pb(2)-Sb(1) bond length is 1.33 Å. Sb(1) is bonded in a linear geometry to one Pb(1) and one Pb(2) atom.
