Co(hmba)3[Co(SCN)4] crystals were synthesized by following a procedure adapted from previous reports. 17 All crystals were stored in a desiccator or under vacuum (<10 mbar) and slightly elevated temperatures (~30-40ºC). Glasses from the Co(hmba)3[CoBr4] system, which were produced by melt-quenching and found to be X-ray amorphous (Figure ), were always produced immediately prior to or during analysis to avoid effects of storage (e.g., possible crystallization or unwanted hydration effects). We tested the stability of the Co(hmba)3[CoBr4] melt by melting the crystal for 2, 5, 10, 20, and 40 mins, finding no decomposition to the organic linker, as seen from 1 HNMR results in Figure and an example of an interpretated 1 HNMR spectrum in Figure .
