Abstract: In the crystal structure of the title compound, C₁₇H₁₇ClN₄O, the existence of only one 2-imino-oxo of the five possible N-amino-imino/O-keto-hydroxy tautomers is observed and the dihedral angle between the aromatic rings is 29.78 (11)°. The molecular conformation is stabilized by intramolecular C-HN, N-HO and C-HO hydrogen bonds, in each case generating a six-membered ring. In the crystal structure, the glide-plane-related molecules are linked into C(4) amide chains by intermolecular N-HO hydrogen bonds, and an intermolecular C-HO link also occurs.
