The compound described by Dy2Fe12Al5 crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 18-coordinate geometry to six equivalent Fe(1) and twelve equivalent Fe(2) atoms. In the second Dy site, Dy(2) is bonded in a 20-coordinate geometry to six equivalent Fe(1), six equivalent Fe(2), two equivalent Al(1), and six equivalent Al(2) atoms. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 12-coordinate geometry to one Dy(1), one Dy(2), two equivalent Fe(1), four equivalent Fe(2), two equivalent Al(1), and two equivalent Al(2) atoms. In the second Fe site, Fe(2) is bonded in a 12-coordinate geometry to one Dy(2), two equivalent Dy(1), two equivalent Fe(2), four equivalent Fe(1), one Al(1), and two equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 14-coordinate geometry to one Dy(2), three equivalent Fe(2), six equivalent Fe(1), one Al(1), and three equivalent Al(2) atoms. In the second Al site, Al(2) is bonded to two equivalent Dy(2), four equivalent Fe(1), four equivalent Fe(2), and two equivalent Al(1) atoms to form a mixture of distorted corner and face-sharing AlDy2Al2Fe8 cuboctahedra. is represented by the Crystallographic Information File (CIF) [CIF]
