Crystal structure and oxygen storage properties of A-site ordered BaY 1 - xPrxMn2O5 + δ (x = 0, 0.25, 0.5, 0.75 and 1) perovskite-type oxides are reported, showing almost complete and reversible change (Δδ > 0.94 mol mol- 1) occurring between fully reduced BaY1 - xPrxMn 2O5 and oxidized BaY1 - xPrxMn 2O6 during reduction in 5 vol.% H2 in Ar atmosphere and oxidation in air at 500 °C. All reduced compounds, as well as oxidized ones for x.
