CoCu2Pb crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one CoCu2Pb cluster. Co(1) is bonded in a distorted L-shaped geometry to one Cu(1) and one Pb(1) atom. The Co(1)-Cu(1) bond length is 1.09 Å. The Co(1)-Pb(1) bond length is 1.64 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a distorted single-bond geometry to one Co(1) atom. In the second Cu site, Cu(2) is bonded in a 1-coordinate geometry to one Pb(1) atom. The Cu(2)-Pb(1) bond length is 2.01 Å. Pb(1) is bonded in a distorted bent 150 degrees geometry to one Co(1) and one Cu(2) atom.
