Abstract: In the title compound, C₁₆H₁₄N₄O₄S·H₂O, the benzene and pyridine rings make a dihedral angle of 85.8 (1)°. Both enantiomers of the chiral title compound are statistically disordered over the same position in the unit cell. The methyl and carbonyl group attached to the stereogenic center (C₅ of the thiazolidine ring) were therefore refined with common site-occupation factors of 0.531 (9) and 0.469 (9), respectively, for each stereoisomer. In the crystal, intermolecular N-HO, O-HO and O-HN hydrogen bonds link the molecules, forming a three-dimensional supramolecular network. The crystal structure further shows - stacking interactions [centroid-centroid distance = 3.5063 (13) Å] between the pyridine rings.
