Dy(MnAl)6 crystallizes in the orthorhombic Immm space group. Dy(1) is bonded in a 20-coordinate geometry to four equivalent Mn(2), eight equivalent Mn(1), two equivalent Al(1), two equivalent Al(2), and four equivalent Al(3) atoms. There are two inequivalent Mn sites.

There are three inequivalent Al sites. In the first Al site, Al(1) is bonded in a 10-coordinate geometry to one Dy(1), two equivalent Mn(2), four equivalent Mn(1), one Al(1), and two equivalent Al(3) atoms. In the second Al site, Al(2) is bonded in a 8-coordinate geometry to one Dy(1), two equivalent Mn(2), four equivalent Mn(1), one Al(2), and two equivalent Al(3) atoms. In the third Al site, Al(3) is bonded in a 12-coordinate geometry to two equivalent Dy(1), two equivalent Mn(2), four equivalent Mn(1), two equivalent Al(1), and two equivalent Al(2) atoms.
