Zusammenfassung:	For the first time, DySrAlO 4 of K 2 NiF 4 -type structure was synthesized. The parameters of DySrAlO 4 elementary unit cell are determined as follows: a = 0.368 (4) nm, c = 1.229 (2) nm, V = 0.166 (4) nm 3 . The research of the complex aluminates Ln SrAlO 4 ( Ln = Nd, Gd, Dy) solid-state process demonstrated the change of the formation mechanism among Ln SrAlO 4 ( Ln = Nd, Gd, Dy) series from DySrAlO 4 oxide. The performed analysis provided a possibility to realize why chemists couldn’t get DySrAlO 4 for a long period of time.
