In order to generate atomistic models of ZIF glasses, we have decided to follow the meltquenching route, reproducing with molecular dynamics simulations the increase in temperature to produce a liquid ZIF, 7 followed by a quench back to room temperature to produce a glass. This general procedure, mimicking the experimental reality (albeit at length and time scales that are much shorter), has long been used to model the structure of multiple glass-forming materials such as chalcogenide compounds or silicates. It has previously been used in simulations of ZIFs, both with a reactive force field 13 and with ab initio MD. 10
