Crystal structure of 2-(morpholino)ethylammonium picrate monohydrate.

The title compound, C₆H₁₅N₂O⁺·C₆H₂N₃O₇^-·H₂O, was synthesized via slow evaporation of an aqueous solution of picric acid with the substituted morpholine base and crystallized with one cation (C₆H₁₅N₂O)⁺, one anion (C₆H₂N₃O₇)^- and a water molecule in the asymmetric unit. The morpholine ring in the cation adopts a chair conformation. The structure is stabilized by C--H...O, O--H...O, O--H...N and N--H...O hydrogen-bonding interactions and π-π stacking. The intermolecular interactions of the synthesized compound were quantified by Hirshfeld surface analysis. [ABSTRACT FROM AUTHOR]
