Co4GaPb crystallizes in the trigonal R3m space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 6-coordinate geometry to one Co(2), two equivalent Co(1), one Ga(1), and two equivalent Pb(1) atoms. The Co(1)-Co(2) bond length is 2.08 Å. Both Co(1)-Co(1) bond lengths are 1.20 Å. The Co(1)-Ga(1) bond length is 2.69 Å. There is one shorter (2.61 Å) and one longer (2.67 Å) Co(1)-Pb(1) bond length. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Co(1), three equivalent Ga(1), and three equivalent Pb(1) atoms. All Co(2)-Ga(1) bond lengths are 2.89 Å. All Co(2)-Pb(1) bond lengths are 2.90 Å. Ga(1) is bonded in a 10-coordinate geometry to three equivalent Co(1), three equivalent Co(2), and four equivalent Pb(1) atoms. There are three shorter (3.01 Å) and one longer (3.07 Å) Ga(1)-Pb(1) bond length. Pb(1) is bonded in a 13-coordinate geometry to three equivalent Co(2), six equivalent Co(1), and four equivalent Ga(1) atoms.
