Crystal structure of 2-(morpholino)ethylammonium picrate monohydrate

Abstract

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.
