Dy2ScFe is Heusler structured and crystallizes in the trigonal R3m space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 7-coordinate geometry to four equivalent Sc(1) and four equivalent Fe(1) atoms. There are three shorter (2.92 Å) and one longer (3.61 Å) Dy(1)-Sc(1) bond length. There is one shorter (2.87 Å) and three longer (3.12 Å) Dy(1)-Fe(1) bond lengths. In the second Dy site, Dy(2) is bonded in a 8-coordinate geometry to four equivalent Sc(1) and four equivalent Fe(1) atoms. There is one shorter (2.87 Å) and three longer (3.12 Å) Dy(2)-Sc(1) bond lengths. There is one shorter (2.87 Å) and three longer (3.12 Å) Dy(2)-Fe(1) bond lengths. Sc(1) is bonded in a 11-coordinate geometry to four equivalent Dy(1), four equivalent Dy(2), and three equivalent Fe(1) atoms. All Sc(1)-Fe(1) bond lengths are 3.33 Å. Fe(1) is bonded in a 8-coordinate geometry to four equivalent Dy(1), four equivalent Dy(2), and three equivalent Sc(1) atoms.
