Morpholin-4-ium hydrogen L-tartrate monohydrate

In the title compound, C₄H₁₀NO⁺·C₄H₅O₆⁻·H₂O, the morpholine ring adopts a chair conformation. In the crystal, the tartrate anions are linked via O—H...O hydrogen bonds, forming chains propagating along [101]. These chains are linked via N—H...O and O—H...O hydrogen bonds, involving the morpholinium cation and the water molecule, forming a three-dimensional network.
