Abstract: A pronounced enthalpy release occurs around 1.38 Tg in the prototypical metal-organic framework glass formed from ZIF-4 [Zn(C3H3N2)2], but there is no sign for any crystallization (i.e., long-range ordering) taking place. This behavior is in strong contrast to that for other families of melt-quenched glasses.
