RuPb2Bi crystallizes in the monoclinic Pm space group. Ru(1) is bonded in a 8-coordinate geometry to four equivalent Ru(1), two equivalent Pb(1), and two equivalent Pb(2) atoms. All Ru(1)-Ru(1) bond lengths are 3.36 Å. There is one shorter (2.57 Å) and one longer (3.15 Å) Ru(1)-Pb(1) bond length. There is one shorter (2.90 Å) and one longer (3.42 Å) Ru(1)-Pb(2) bond length. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 1-coordinate geometry to two equivalent Ru(1) and one Bi(1) atom. The Pb(1)-Bi(1) bond length is 2.34 Å. In the second Pb site, Pb(2) is bonded in a 1-coordinate geometry to two equivalent Ru(1) and one Bi(1) atom. The Pb(2)-Bi(1) bond length is 2.34 Å. Bi(1) is bonded in a 2-coordinate geometry to one Pb(1) and one Pb(2) atom.
