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

products exhibit good thermal stabilities with decomposition temperatures above 200 °C. The detonation pressure values calculated for these compounds range from 17.0 to 28.3 GPa, and the detonation velocities range from 6906 to 8210 m s−1. These values suggest that the guanylhydrazone substituted furoxan energeticderivatives could be potential candidates for thermallystableenergetic materials.
