BeRePbSn crystallizes in the trigonal R3m space group. Be(1) is bonded in a single-bond geometry to three equivalent Re(1), one Pb(1), and three equivalent Sn(1) atoms. All Be(1)-Re(1) bond lengths are 2.80 Å. The Be(1)-Pb(1) bond length is 1.17 Å. All Be(1)-Sn(1) bond lengths are 2.88 Å. Re(1) is bonded in a 10-coordinate geometry to three equivalent Be(1), three equivalent Pb(1), and four equivalent Sn(1) atoms. All Re(1)-Pb(1) bond lengths are 2.88 Å. There are three shorter (2.80 Å) and one longer (3.54 Å) Re(1)-Sn(1) bond length. Pb(1) is bonded in a single-bond geometry to one Be(1), three equivalent Re(1), and four equivalent Sn(1) atoms. There are three shorter (2.80 Å) and one longer (3.54 Å) Pb(1)-Sn(1) bond length. Sn(1) is bonded in a 11-coordinate geometry to three equivalent Be(1), four equivalent Re(1), and four equivalent Pb(1) atoms.
