Be Pb Pb Cl
BePb2Cl is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BePb2Cl cluster. Be(1) is bonded in a single-bond geometry to one Pb(1) atom. The Be(1)-Pb(1) bond length is 1.57 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a distorted bent 150 degrees geometry to one Be(1) and one Pb(2) atom. The Pb(1)-Pb(2) bond length is 0.55 Å. In the second Pb site, Pb(2) is bonded in a water-like geometry to one Pb(1) and one Cl(1) atom. The Pb(2)-Cl(1) bond length is 1.31 Å. Cl(1) is bonded in a single-bond geometry to one Pb(2) atom.
