| Summary: | The crystal of the title Schiff base compound, C20H18ClN3O3·H2O, was twinned by a twofold rotation about (100). The asymmetric unit contains two crystallographically independent molecules with similar conformations, and two water molecules. The C=N—N angles of 115.7 (6) and 116.2 (6)° are significantly smaller than the ideal value of 120° expected for sp2-hybridized N atoms and the dihedral angles between the benzene ring and quinoline ring system in the two molecules are 52.5 (7) and 53.9 (7)°. The molecules aggregate via C—Cl...π and π–π interactions [centroid–centroid distances = 3.696 (5)–3.892 (5) Å] and weak C—H...O interactions as parallel sheets, which are further linked by water molecules through N—H...O and O—H...O hydrogen bonds into a supramolecular two-dimensional network. |
