Fe Co Bi Pb
FeCoPbBi crystallizes in the trigonal R3m space group. Fe(1) is bonded in a 1-coordinate geometry to four equivalent Co(1) and four equivalent Pb(1) atoms. There are three shorter (2.99 Å) and one longer (3.11 Å) Fe(1)-Co(1) bond length. There is one shorter (2.73 Å) and three longer (3.13 Å) Fe(1)-Pb(1) bond lengths. Co(1) is bonded in a 11-coordinate geometry to four equivalent Fe(1), three equivalent Pb(1), and four equivalent Bi(1) atoms. All Co(1)-Pb(1) bond lengths are 3.38 Å. There are three shorter (2.99 Å) and one longer (3.11 Å) Co(1)-Bi(1) bond length. Pb(1) is bonded in a 8-coordinate geometry to four equivalent Fe(1), three equivalent Co(1), and four equivalent Bi(1) atoms. There are three shorter (2.99 Å) and one longer (3.11 Å) Pb(1)-Bi(1) bond length. Bi(1) is bonded in a distorted body-centered cubic geometry to four equivalent Co(1) and four equivalent Pb(1) atoms.
