Ru4CoPb crystallizes in the trigonal R3m space group. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a 2-coordinate geometry to one Ru(2), two equivalent Ru(1), two equivalent Co(1), and two equivalent Pb(1) atoms. The Ru(1)-Ru(2) bond length is 1.47 Å. Both Ru(1)-Ru(1) bond lengths are 0.85 Å. Both Ru(1)-Co(1) bond lengths are 2.84 Å. There is one shorter (1.99 Å) and one longer (3.37 Å) Ru(1)-Pb(1) bond length. In the second Ru site, Ru(2) is bonded in a 10-coordinate geometry to three equivalent Ru(1), four equivalent Co(1), and three equivalent Pb(1) atoms. There are three shorter (3.05 Å) and one longer (3.50 Å) Ru(2)-Co(1) bond length. All Ru(2)-Pb(1) bond lengths are 3.10 Å. Co(1) is bonded in a 13-coordinate geometry to four equivalent Ru(2), six equivalent Ru(1), and three equivalent Pb(1) atoms. All Co(1)-Pb(1) bond lengths are 3.37 Å. Pb(1) is bonded in a 12-coordinate geometry to three equivalent Ru(2), six equivalent Ru(1), and three equivalent Co(1) atoms.
