Fig. 2. PXRD data collected for the as-synthesised crystals 1-DMF (black), and subsequent to solvent exchange with MeOH (1-MeOH, blue). The data collected after the activation processes for 1-MeOH (leading to 1-a, red) and 1-THF (leading to 1-b, grey) are shown. The diffractogram for 1-THF is shown in navy blue.
