The structure described by Dy2Fe14Al3 crystallizes in the trigonal R-3m space group. Dy(1) is bonded in a 19-coordinate geometry to one Fe(3), six equivalent Fe(1), nine equivalent Fe(2), and three equivalent Al(1) atoms. There are three inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 12-coordinate geometry to two equivalent Dy(1), two equivalent Fe(1), two equivalent Fe(3), four equivalent Fe(2), and two equivalent Al(1) atoms. In the second Fe site, Fe(2) is bonded to three equivalent Dy(1), one Fe(3), two equivalent Fe(2), four equivalent Fe(1), and two equivalent Al(1) atoms to form a mixture of distorted corner, face, and edge-sharing FeDy3Al2Fe7 cuboctahedra. In the third Fe site, Fe(3) is bonded in a 14-coordinate geometry to one Dy(1), one Fe(3), three equivalent Fe(2), six equivalent Fe(1), and three equivalent Al(1) atoms. Al(1) is bonded in a 10-coordinate geometry to two equivalent Dy(1), two equivalent Fe(3), four equivalent Fe(1), and four equivalent Fe(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
