Crystal structure of 2-(morpholino)ethyl-ammonium 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 mol-ecule 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 inter-actions and π-π stacking. The inter-molecular inter-actions of the synthesized compound were qu-anti-fied by Hirshfeld surface analysis.
