Materials Data on BePb3 by Materials Project
Be(Pb)3 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional and consists of two beryllium molecules and one Pb framework. In the Pb framework, there are two inequivalent Pb sites. In the first Pb site, Pb is bonded in a 8-coordinate geometry to eight Pb atoms. There are four shorter (3.29 Å) and four longer (3.44 Å) Pb–Pb bond lengths. In the second Pb site, Pb is bonded in a 12-coordinate geometry to eight equivalent Pb atoms.
