Zeitschrift für anorganische und allgemeine Chemie, EarlyView.La0.5Sr3.5Fe3O7.5F2.6, a rare n = 3 Ruddlesden–Popper oxyfluoride, exhibits robust antiferromagnetism across a wide temperature range from 1.7 to 470 K. Temperature‐dependent neutron diffraction reveals an orthorhombic nuclear and a monoclinic magnetic structure, while Mößbauer spectroscopy shows persistent short‐range magnetic order up to 525 K.
