| Özet |
| The title compounds, (Z)-4-(2,6-dichlorophenyldiazenyl)-6-{[1,3-dihydroxy-2-(hydroxymethyl)propan-2-ylamino]methylene}-2-methoxycyclohexa-2,4-dienone, C18H19Cl2N3O5, (I), (Z)-6-{[1,3-dihydroxy-2-(hydroxymethyl)propan-2-ylamino]methylene}-2-methoxy-4-(3-methoxyphenyldiazenyl)cyclohexa-2,4-dienone, C19H23N3O6, (II), and (Z)-6-{[1,3-dihydroxy-2-(hydroxymethyl)propan-2-ylamino]methylene}-2-methoxy-4-(4-methoxyphenyldiazenyl)cyclohexa-2,4-dienone, C19H23N3O6, (III), all adopt the keto–amine tautomeric form, and the hydroxy H atoms are located on the N atom in all three compounds. Strong intramolecular N—H⋯O hydrogen bonds arise as a result of the shifts achieved by the hydroxy H atoms of the Schiff bases to the N atoms. Positional disorder was observed in molecules (II) and (III). In all three compounds, C—H⋯π and π–π interactions affect the packing of the molecules. The … |
