High-resolution neutron powder diffraction study of Dy₂Fe₉Al₈ has been carried out at 65K. The crystallographic parameters and magnetic moments were determined by Rietveld profile fitting calculation. The results showed that Dy₂Fe₉Al₈ crystallized in the rhombohedral Th₂Zn₁₇ type structure. The aluminum atoms were distributed randomly at positions 18f, 18h and 6c. The magnetic moments of all iron atoms were parallel to the six-fold axis and couple antiferromagnetically to the moment of Dy.
