Abstract

The mol­ecular structure of the title compound, C21H15ClN2O2, features one strong intra­molecular N—H⋯O resonance-assisted hydrogen bond (RAHB). In the crystal, mol­ecules form inversion-related dimers via pairs of weak inter­molecular N—H⋯O contacts. These dimers are further stabilized via three weak C—H⋯O contacts, developing the three-dimensional structure.
