ReRuPb2 crystallizes in the triclinic P1 space group. Re(1) is bonded in a 2-coordinate geometry to one Ru(1), one Pb(1), and one Pb(2) atom. The Re(1)-Ru(1) bond length is 2.36 Å. The Re(1)-Pb(1) bond length is 0.89 Å. The Re(1)-Pb(2) bond length is 1.73 Å. Ru(1) is bonded in a 5-coordinate geometry to one Re(1), two equivalent Pb(1), and two equivalent Pb(2) atoms. There is one shorter (2.93 Å) and one longer (2.95 Å) Ru(1)-Pb(1) bond length. There is one shorter (2.52 Å) and one longer (3.18 Å) Ru(1)-Pb(2) bond length. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a single-bond geometry to one Re(1) and two equivalent Ru(1) atoms. In the second Pb site, Pb(2) is bonded in a single-bond geometry to one Re(1) and two equivalent Ru(1) atoms.
