BePbP2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BePbP2 cluster. Be(1) is bonded in a 3-coordinate geometry to one Pb(1), one P(1), and one P(2) atom. The Be(1)-Pb(1) bond length is 2.04 Å. The Be(1)-P(1) bond length is 1.91 Å. The Be(1)-P(2) bond length is 2.09 Å. Pb(1) is bonded in a distorted L-shaped geometry to one Be(1), one P(1), and one P(2) atom. The Pb(1)-P(1) bond length is 0.64 Å. The Pb(1)-P(2) bond length is 1.28 Å. There are two inequivalent P sites. In the first P site, P(1) is bonded in a distorted single-bond geometry to one Be(1) and one Pb(1) atom. In the second P site, P(2) is bonded in a 1-coordinate geometry to one Be(1) and one Pb(1) atom.
