Reply to 'Structural and magnetic behavior of the cubic oxyfluoride SrFeO2F studied by neutron diffraction'

In this article we comment on the results published by Thompson et al. (, J. Solid State Chem. 219 (2014) 173–178) on the crystal structure of SrFeO 2 F, who claim the compound to crystallize in the cubic space group Pm -3 m . We give a more detailed explanation of the determination of our previously reported structural model with Imma symmetry (Clemens et al., J. Solid State Chem. 206 (2013) 158–169), with addition of variable temperature XRD measurements with high counting time to provide unambiguous evidence for the Imma model being correct for our sample.
