We investigated the N-Zn-N angle distribution (plotted on Figure ): the MLP glass demonstrates an excellent reproduction of the ab initio data, which is crucial because that property is key to the features of ZIFs, and is not well reproduced by other levels of description (such as ReaxFF). The angular PMF shown on Figure further confirms this accuracy, showing minimal deviations for angles away from the 109.5 • of the Zn(Im) 4 tetrahedral structure. We then computed the porosity of the glasses (see Figure ) and found a total porous volume of 61 cm 3 kg -1 for the MLP glass, comprised between the 54 cm 3 kg -1 of the crystal and 68 cm 3 kg -1 of the ab initio glass. This is in good agreement with the experimental measurements of the porosity of a ZIF-4 glass made by positron annihilation lifetime spectroscopy (PALS). Finally, we investigated the differences in the medium-range order of the glasses, by examining the coordination network built from the alternating Zn-Im units. we first calculated the average Zn-N coordination numbers and found a coordination of 3.93 for the MLP glass, the same value as the ab initio glass. We also computed Zn-Im ring statistics, to characterize the topology at a larger scale. Figure evidences that both glasses have topologies that de-viate from the crystal's perfectly defined 8, 12 and 16-membered rings. While not identical, the two glass models display rather similar topologies. Overall, these elements show that the glass model generated with our MLP reproduces well many properties of the ab initio glasses, all the more when compared to how ReaxFF fares. Moreover, the MLP glass has characteristics in line with known experimental data, providing strong evidence that aZIF models can be generated by MD simulations of meltquenching with chemically accurate force fields.
