Be2ScPb is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Be2ScPb clusters. There are two inequivalent Be sites. In the first Be site, Be(1) is bonded in a distorted linear geometry to one Be(2) and one Sc(1) atom. The Be(1)-Be(2) bond length is 0.48 Å. The Be(1)-Sc(1) bond length is 0.14 Å. In the second Be site, Be(2) is bonded in a distorted linear geometry to one Be(1) and one Pb(1) atom. The Be(2)-Pb(1) bond length is 0.65 Å. Sc(1) is bonded in a single-bond geometry to one Be(1) atom. Pb(1) is bonded in a single-bond geometry to one Be(2) atom.
