To further clarify the glass transition behavior of the Co(hmba)3[CoBr4] glasses, we performed annealing experiments at 0.9Tg of both pristine and hydrated samples. Based on the DSC measurements of these samples, we find for both the pristine and hydrated glasses that their fictive temperatures (Tf, determined in a similar manner as Tg from calorimetry, yet with varying heating rates) decrease, and the endothermic overshoot of the glass transition increases with annealing duration (Figure ). This is consistent with previous findings for other glass families and is a consequence of the decrease in the overall enthalpy of the system through the hopping between metastable states and, upon such heating, into local minima of the potential energy surface. Additionally, we determined the liquid fragility (m), which quantifies the extent of non-Arrhenius temperature dependence of viscosity at Tg. This was done on both pristine and hydrated glasses using a DSC-based method. Specifically, glasses were heated from below to above Tg at a range of heating rates (5, 10, 15, 20, 25, and 30 K min -1 ) and the shift in fictive temperature was recorded.
