ScTaPb crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ScTaPb clusters. Sc(1) is bonded in a single-bond geometry to one Ta(1) atom. The Sc(1)-Ta(1) bond length is 0.76 Å. Ta(1) is bonded in a distorted single-bond geometry to one Sc(1) and one Pb(1) atom. The Ta(1)-Pb(1) bond length is 2.55 Å. Pb(1) is bonded in a single-bond geometry to one Ta(1) atom.
