Y6FeBi2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 4-coordinate geometry to two equivalent Fe(1) and two equivalent Bi(1) atoms. In the second Y site, Y(2) is bonded in a 5-coordinate geometry to one Fe(1) and four equivalent Bi(1) atoms. Fe(1) is bonded in a 9-coordinate geometry to three equivalent Y(2) and six equivalent Y(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to three equivalent Y(1) and six equivalent Y(2) atoms.
Y6FeBi2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 4-coordinate geometry to two equivalent Fe(1) and two equivalent Bi(1) atoms. Both Y(1)-Fe(1) bond lengths are 2.87 Å. Both Y(1)-Bi(1) bond lengths are 3.29 Å. In the second Y site, Y(2) is bonded in a 5-coordinate geometry to one Fe(1) and four equivalent Bi(1) atoms. The Y(2)-Fe(1) bond length is 3.31 Å. All Y(2)-Bi(1) bond lengths are 3.32 Å. Fe(1) is bonded in a 9-coordinate geometry to three equivalent Y(2) and six equivalent Y(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to three equivalent Y(1) and six equivalent Y(2) atoms.
