BeAgPb2 is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeAgPb2 cluster. Be(1) is bonded in a single-bond geometry to one Pb(1) atom. The Be(1)-Pb(1) bond length is 1.02 Å. Ag(1) is bonded in a distorted water-like geometry to one Pb(1) and one Pb(2) atom. The Ag(1)-Pb(1) bond length is 1.01 Å. The Ag(1)-Pb(2) bond length is 0.40 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a bent 150 degrees geometry to one Be(1) and one Ag(1) atom. In the second Pb site, Pb(2) is bonded in a single-bond geometry to one Ag(1) atom.
