چکیده

In the title compound, C(17)H(19)NO(2), the dihedral angle between the two aromatic rings is 26.02 (5)°. One phenol O atom is deprotonated and the N atom of the azomethine unit carries the H atom, forming an intra-molecular hydrogen bond. The packing is stabilized by an O-H⋯O hydrogen bond.

(Z)-6-[(5-Chloro-2-hydroxy­anilino)­methyl­ene]-4-methoxy­cyclo­hexa-2,4-dienone 0.25-hydrate

The title compound, C(14)H(12)ClNO(3)·0.25H(2)O, 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. π-π contacts between benz...

3-Diethyl­amino-6-[(Z)-(4-hy­droxy­anilino)methyl­idene]cyclo­hexa-2,4-dienone

In the mol-ecule of the title compound, C(17)H(20)N(2)O(2), the aromatic rings are oriented at a dihedral angle of 6.23 (22)°. Intra-molecular N-H⋯O hydrogen bonding involving the amine H atom and the carbonyl O atom affects the conformation of the mol-ecule. One of the ethyl arms is disordered over two conformations, with occupancies of 0.59 (2) and 0.41 (2). The crystal packing is stabilized ...
