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 intra­molecular N—H⋯(O,O) hydrogen bonds result in the formation of planar six- and five-membered rings. In the crystal structure, inter­molecular O—H⋯O and C—H⋯O hydrogen bonds link the mol­ecules into chains. π–π contacts between benzene rings [centroid–centroid distance = 3.5065 (9) Å] may further stabilize the structure. There also exists a weak C—H⋯π inter­action.
