Finally, we investigated the differences in the medium-range order of the glasses, highlighted by their contrasting structure factors shown on Figure , by examining the coordination network built from the alternating Zn-Im (imidazolate) units. We first calculated the average Zn-N coordination numbers and found a lower coordination of 3.85 for the ReaxFF glass compared to 3.93 for the ab initio glass, confirming the ReaxFF tendency to underconstrain Zn-N bonds.
