CuPb2Sb is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CuPb2Sb cluster. Cu(1) is bonded in a single-bond geometry to one Pb(1), one Pb(2), and one Sb(1) atom. The Cu(1)-Pb(1) bond length is 2.11 Å. The Cu(1)-Pb(2) bond length is 0.09 Å. The Cu(1)-Sb(1) bond length is 2.11 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 2-coordinate geometry to one Cu(1) and one Sb(1) atom. The Pb(1)-Sb(1) bond length is 2.00 Å. In the second Pb site, Pb(2) is bonded in a single-bond geometry to one Cu(1) atom. Sb(1) is bonded in a 2-coordinate geometry to one Cu(1) and one Pb(1) atom.
