    • 2O were grown from 96% ethanol. Unfortunately, it is not yet possible to obtain suitable single-crystals in anhydrous conditions. In fact, the crystal packing of the macrocycle it is dominated by H-bonding involving water molecules. It would be relevant however to grow single-crystals in anhydrous conditions to see if a packing geometry dominated by π-π stacking interactions between positively and negatively charge rings would result instead
