The crystal structure described by DyAl crystallizes in the orthorhombic Pbcm space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in a 6-coordinate geometry to four equivalent Al(1) and four equivalent Al(2) atoms. In the second Dy site, Dy(2) is bonded in a 8-coordinate geometry to four equivalent Al(1) and four equivalent Al(2) atoms. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded to four equivalent Dy(1), four equivalent Dy(2), two equivalent Al(1), and two equivalent Al(2) atoms to form a mixture of distorted edge, corner, and face-sharing AlDy8Al4 cuboctahedra. In the second Al site, Al(2) is bonded in a 10-coordinate geometry to four equivalent Dy(1), four equivalent Dy(2), and two equivalent Al(1) atoms. is represented by the CIF file [CIF]
