effective approach to sulfateseparation from aqueous solutions is based on the crystallization of extended [SO4(H2O)52−]n sulfate–waterclusters with a bis(guanidinium) ligand. The ligand was generated in situ by hydrazone condensation in water, thereby bypassing the need for elaborate syntheses, tedious purifications, and organic solvents. Crystallization of sulfate–waterclusters represents an alternative
