However, we observe a very weak overall global correlation between DE(oxo) and DE(HAT) reaction energies (Pearson's r = -0.28, Figure ). This lack of correlation has also been observed in transition metal complexes, and has been attributed to variations caused by changing metal oxidation and spin states or geometric distortions of the metal with respect to the ligands. For MOFs typically studied in a single spin state, LFERs have been suggested for DE(oxo) vs. DE(HAT) in direct methane to methanol conversion, but our results show that they do not hold across all metals in our dataset.
