Morpholin-4-ium hydrogen tartrate

In the title molecular salt, C4H10NO+·C4H5O6 , the morpholinium cation adopts a chair conformation. The conformation of the C—C—C—C backbone of the monotartrate anion is close to anti [torsion angle = 173.18 (17)°], which is supported by two intramolecular O—H...O hydrogen bonds. In the crystal, the components are linked by N—H—O and O—H—O hydrogen bonds, generating (001) sheets.
