Isolated manganese (IV) has been stabilized and characterized within Sr0.50La1.50Li0.50Mn0.50O4 oxide with the K2NiF4 structure. 1/1 cationic order has been identified in the perovskite-type layers by X-ray diffraction and Mössbauer resonance spectroscopy in the iron doped phase for the Li and Mn ions.
