Dy6FeBi2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 4-coordinate geometry to two equivalent Fe(1) and two equivalent Bi(1) atoms. In the second Dy site, Dy(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 Dy(2) and six equivalent Dy(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to three equivalent Dy(1) and six equivalent Dy(2) atoms.
Dy6FeBi2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 4-coordinate geometry to two equivalent Fe(1) and two equivalent Bi(1) atoms. Both Dy(1)-Fe(1) bond lengths are 2.86 Å. Both Dy(1)-Bi(1) bond lengths are 3.28 Å. In the second Dy site, Dy(2) is bonded in a 5-coordinate geometry to one Fe(1) and four equivalent Bi(1) atoms. The Dy(2)-Fe(1) bond length is 3.30 Å. All Dy(2)-Bi(1) bond lengths are 3.31 Å. Fe(1) is bonded in a 9-coordinate geometry to three equivalent Dy(2) and six equivalent Dy(1) atoms. Bi(1) is bonded in a 9-coordinate geometry to three equivalent Dy(1) and six equivalent Dy(2) atoms.
