Clemens et al. reported on the results published by us (Thompson et al. J. Solid State Chem. 219 (2014) 173-178) on the crystal structure of SrFeO2F, which they suggest to actually crystallize in the orthorhombic space group Imma rather than the cubic Pm-3m structure at lower temperatures (Clemens et al. J. Solid State Chem. (2015), http://dx.doi.org/10.1016/j.jssc.2015.02.022). In this report, we provide evidence to support their claim that at lower temperatures (<523K) the structure is evidently Imma. Furthermore, we will highlight the significance of our previous report and comment on the proposed explanations of the magnetic behavior of SrFeO2F reported by both groups.
