The pressure dependence of the crystal structure of Sr 2 Fe 2 O 5 has been studied at room temperature by angle-dispersive synchrotron X-ray powder di4raction and 57 Fe MoK ssbauer spectroscopy using diamond anvil cell techniques. Between 11 and 14 GPa the low-pressure brownmillerite-type structure
