Co Co Co Co Ru Pb
RuCo4Pb crystallizes in the trigonal R3m space group. Ru(1) is bonded in a 4-coordinate geometry to three equivalent Co(1), three equivalent Co(2), and one Pb(1) atom. All Ru(1)-Co(1) bond lengths are 2.15 Å. All Ru(1)-Co(2) bond lengths are 3.00 Å. The Ru(1)-Pb(1) bond length is 1.89 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 4-coordinate geometry to one Ru(1), one Co(2), two equivalent Co(1), and one Pb(1) atom. The Co(1)-Co(2) bond length is 2.34 Å. Both Co(1)-Co(1) bond lengths are 1.35 Å. The Co(1)-Pb(1) bond length is 2.35 Å. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Ru(1), three equivalent Co(1), and three equivalent Pb(1) atoms. All Co(2)-Pb(1) bond lengths are 2.99 Å. Pb(1) is bonded in a 4-coordinate geometry to one Ru(1), three equivalent Co(1), and three equivalent Co(2) atoms.
