Abstract

The title compound, C14H12ClN3O2, displays an E conformation with respect to the C=N double bond. The dihedral angle between the benzene rings is 41.3 (5)°. The mol­ecular structure is stabilized by an intra­molecular O—H⋯N hydrogen bond. In the crystal, N—H⋯O and weak N—H⋯Cl hydrogen bonds link the mol­ecules into a three-dimensional architecture. In addition, there are weak C—H⋯π stacking inter­actions.
