Abstract

A new layered manganese oxide, Sr₂MnGaO₅, has been synthesised and Rietveld analysis of X-ray powder diffraction data has shown it to be an oxygen deficient perovskite with the brownmillerite structure: a = 5.5033(6) Å, b = 16.234(2) Å, c = 5.3717(6) Å. Incomplete order of the oxygen vacancies is best described using the space group Icmm. The oxygen content can readily be varied to form Sr₂MnGaO_5+δ (0≤δ≤0.5) to provide Mn oxidation states between Mn(III) and Mn(IV).
