BeRh2Pb is Indium-like structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one BeRh2Pb cluster. Be(1) is bonded in a 2-coordinate geometry to one Rh(2) and one Pb(1) atom. The Be(1)-Rh(2) bond length is 1.10 Å. The Be(1)-Pb(1) bond length is 1.68 Å. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a single-bond geometry to one Pb(1) atom. The Rh(1)-Pb(1) bond length is 0.75 Å. In the second Rh site, Rh(2) is bonded in a single-bond geometry to one Be(1) atom. Pb(1) is bonded in a 1-coordinate geometry to one Be(1) and one Rh(1) atom.
