(Z)-6-[(5-Chloro-2-hydroxy-anilino)-methyl-ene]-4-methoxy-cyclo-hexa-2, 4-dienone 0.25-hydrate

Abstract

The title compound, C14H12ClNO3·0. 25H2O, exists in the keto-amine form, and the aromatic rings are oriented at a dihedral angle of 7.24 (7)°. Bifurcated intra-molecular N - H?(O,O) hydrogen bonds result in the formation of planar six- and five-membered rings. In the crystal structure, inter-molecular O - H?O and C - H?O hydrogen bonds link the mol-ecules into chains. ?-? contacts between benzene rings [centroid-centroid distance = 3.5065 (9) Å] may further stabilize the structure. There also exists a weak C - H?? inter-action.
