BeRe4Pb crystallizes in the trigonal R3m space group. Be(1) is bonded in a single-bond geometry to three equivalent Re(1) and one Pb(1) atom. All Be(1)-Re(1) bond lengths are 2.84 Å. The Be(1)-Pb(1) bond length is 1.79 Å. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 5-coordinate geometry to one Be(1), one Re(2), two equivalent Re(1), and one Pb(1) atom. The Re(1)-Re(2) bond length is 1.16 Å. Both Re(1)-Re(1) bond lengths are 0.67 Å. The Re(1)-Pb(1) bond length is 1.56 Å. In the second Re site, Re(2) is bonded in a 3-coordinate geometry to three equivalent Re(1) atoms. Pb(1) is bonded in a distorted single-bond geometry to one Be(1) and three equivalent Re(1) atoms.
