We found that the manuscript titled “Thermochemistry of stoichiometric rare earth oxyfluorides REOF” (J Am Ceram Soc. 2022;105:1472–1480) contains a mistake. Specifically, an incorrect value was used as electron affinity O to form O2− (ΔH4 in Table S3), leading wrong lattice energies (−U) RE2O3 and REOF Figure 6 S5. Although this mistake affects absolute values −U, which are not discussed manus...
