Co Cu Cu Pb
CoCu2Pb crystallizes in the triclinic P1 space group. Co(1) is bonded in a 2-coordinate geometry to one Cu(1) and one Pb(1) atom. The Co(1)-Cu(1) bond length is 1.99 Å. The Co(1)-Pb(1) bond length is 2.06 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 3-coordinate geometry to one Co(1), one Cu(2), and one Pb(1) atom. The Cu(1)-Cu(2) bond length is 1.41 Å. The Cu(1)-Pb(1) bond length is 2.49 Å. In the second Cu site, Cu(2) is bonded in a 3-coordinate geometry to one Cu(1) and two equivalent Pb(1) atoms. There is one shorter (2.14 Å) and one longer (2.18 Å) Cu(2)-Pb(1) bond length. Pb(1) is bonded in a distorted rectangular see-saw-like geometry to one Co(1), one Cu(1), and two equivalent Cu(2) atoms.
