It also possesses an nia topology, which means it forms a bipartite structure. The MOF with the second-highest selectivity (i.e., 8.6), QOTZEG, contains a single La-containing node in which the metal center is coordinated to eight oxygens from 1,3,5-benzenetricarboxylic acid linkers along with one bound water molecule. Its topology could not be identified (i.e., with the CrystalNets Julia package ), so we note that it is characterized by a P43 space group. Finally, FELWEA presents an interesting case because it forms dual TbO9 and CaO6 nodes connected by 2,2oxydiacetic acid linkers. In its native form, it also contains [Ca(H2O)6] 2+ complexes within its pores that act as charge balancing agents, although these were removed prior to featurization. The ideal ethane selectivity of FELWEA is predicted to be 6.3. We also predicted high-selectivity
