Also, it is important to note that there are many duplicate structures among the selected dataset. For instance, some MOFs were synthesized by different research groups but submitted under different code-names. Those MOFs were kept in the dataset under study, because the activation status and methods might differ. However, in some papers, both the as-synthesized and evacuated structures were reported. In this case, one of the structures was rejected for redundancy. More importantly, some MOFs were reported at various temperatures or pressures. As well, we found few hypothetical MOFs in the CoRE database. Accordingly, these kinds of duplicate submissions were filtered out manually.
