AlPb2P is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one AlPb2P cluster. Al(1) is bonded in a distorted L-shaped geometry to one Pb(1) and one Pb(2) atom. The Al(1)-Pb(1) bond length is 0.61 Å. The Al(1)-Pb(2) bond length is 0.85 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a single-bond geometry to one Al(1) and one P(1) atom. The Pb(1)-P(1) bond length is 2.17 Å. In the second Pb site, Pb(2) is bonded in a single-bond geometry to one Al(1) atom. P(1) is bonded in a single-bond geometry to one Pb(1) atom.
