Al Pb Cl Cl
AlPbCl2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AlPbCl2 cluster. Al(1) is bonded in a 2-coordinate geometry to one Pb(1) and one Cl(2) atom. The Al(1)-Pb(1) bond length is 1.78 Å. The Al(1)-Cl(2) bond length is 2.63 Å. Pb(1) is bonded in a distorted single-bond geometry to one Al(1) and one Cl(1) atom. The Pb(1)-Cl(1) bond length is 0.82 Å. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a single-bond geometry to one Pb(1) atom. In the second Cl site, Cl(2) is bonded in a distorted single-bond geometry to one Al(1) atom.
