Abstract: The rare earth complex oxides Dy0.5Sr1.5MO4(M = Mn, Fe, Co, Ni) were prepared.Their crystal structures have been studied by means of X-ray diffraction technique.The complex oxides with K2NiF4 tetragonal type structure have been obtained.The catalytic property has been characterized with micro-reactor and temperature programed desorption (TPD) technique.Besides, the availability of tolerance factor(t) has been discussed.

Key words: K2NiF4 Sturture, Rare earth complex oxide, Tolerance factor
