Crystal structure of 2-(morpholino)ethyl­ammonium picrate monohydrate

The title compound, C(6)H(15)N(2)O(+)·C(6)H(2)N(3)O(7) (−)·H(2)O, was synthesized via slow evaporation of an aqueous solution of picric acid with the substituted morpholine base and crystallized with one cation (C(6)H(15)N(2)O)(+), one anion (C(6)H(2)N(3)O(7))(−) 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.
