VCu2Pb is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one VCu2Pb cluster. V(1) is bonded in a 2-coordinate geometry to one Cu(1) and one Pb(1) atom. The V(1)-Cu(1) bond length is 0.09 Å. The V(1)-Pb(1) bond length is 0.09 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a single-bond geometry to one V(1), one Cu(2), and one Pb(1) atom. The Cu(1)-Cu(2) bond length is 0.18 Å. The Cu(1)-Pb(1) bond length is 0.08 Å. In the second Cu site, Cu(2) is bonded in a distorted single-bond geometry to one Cu(1) and one Pb(1) atom. The Cu(2)-Pb(1) bond length is 0.18 Å. Pb(1) is bonded in a distorted single-bond geometry to one V(1), one Cu(1), and one Cu(2) atom.
