Abstract
The title compound, C14H12ClNO3 center dot 0.25H(2)O, exists in the keto-amine form, and the aromatic rings are oriented at a dihedral angle of 7.24 (7)degrees. Bifurcated intramolecular N-H center dot center dot center dot(O,O) hydrogen bonds result in the formation of planar six- and five-membered rings. In the crystal structure, intermolecular O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds link the molecules into chains. pi-pi contacts between benzene rings [centroid-centroid distance = 3.5065 (9) angstrom] may further stabilize the structure. There also exists a weak C-H center dot center dot center dot pi interaction.
