Sc6FeSb2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 5-coordinate geometry to one Fe(1) and four equivalent Sb(1) atoms. In the second Sc site, Sc(2) is bonded in a 4-coordinate geometry to two equivalent Fe(1) and two equivalent Sb(1) atoms. Fe(1) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent Sc(2) atoms. Sb(1) is bonded in a 9-coordinate geometry to three equivalent Sc(2) and six equivalent Sc(1) atoms.
Sc6FeSb2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Sc sites. In the first Sc site, Sc(1) is bonded in a 5-coordinate geometry to one Fe(1) and four equivalent Sb(1) atoms. The Sc(1)-Fe(1) bond length is 3.00 Å. All Sc(1)-Sb(1) bond lengths are 3.08 Å. In the second Sc site, Sc(2) is bonded in a 4-coordinate geometry to two equivalent Fe(1) and two equivalent Sb(1) atoms. Both Sc(2)-Fe(1) bond lengths are 2.68 Å. Both Sc(2)-Sb(1) bond lengths are 3.00 Å. Fe(1) is bonded in a 9-coordinate geometry to three equivalent Sc(1) and six equivalent Sc(2) atoms. Sb(1) is bonded in a 9-coordinate geometry to three equivalent Sc(2) and six equivalent Sc(1) atoms.
