To the author?s knowledge, no structural characterization of Nd2NiO4+δ at low pO2 has been previously reported in the literature. In this study ( Fig. 11b), the X-ray diffractograms clearly show that the structure of the nickelate remains orthorhombic over the whole temperature range at low pO2. The best fit of the data was obtained using the Fmmm space group, but further studies would be needed to confirm endoplasmic reticulum (ER) point.
