La Cu Pb Pb
LaCuPb2 crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one LaCuPb2 cluster. La(1) is bonded in a distorted single-bond geometry to one Cu(1) and one Pb(2) atom. The La(1)-Cu(1) bond length is 1.87 Å. The La(1)-Pb(2) bond length is 2.42 Å. Cu(1) is bonded in a distorted single-bond geometry to one La(1), one Pb(1), and one Pb(2) atom. The Cu(1)-Pb(1) bond length is 0.96 Å. The Cu(1)-Pb(2) bond length is 1.87 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a single-bond geometry to one Cu(1) atom. In the second Pb site, Pb(2) is bonded in a 2-coordinate geometry to one La(1) and one Cu(1) atom.
