KScPb2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KScPb2 clusters. K(1) is bonded in a 3-coordinate geometry to one Sc(1) and two equivalent Pb(1) atoms. The K(1)-Sc(1) bond length is 1.16 Å. Both K(1)-Pb(1) bond lengths are 1.10 Å. Sc(1) is bonded in a 3-coordinate geometry to one K(1) and two equivalent Pb(1) atoms. Both Sc(1)-Pb(1) bond lengths are 1.10 Å. Pb(1) is bonded in a 2-coordinate geometry to one K(1) and one Sc(1) atom.
