چکیده
The title compound, C(15)H(15)N(3)O, was obtained by a condensation reaction between o-amino-acetophenone and benzoyl hydrazine. The mol-ecule displays an E configuration about the C=N bond. Intra-molecular N-H⋯N hydrogen bonds are formed between the 2-amino-phenyl and imine groups. In the crystal, dimers are formed between mol-ecules linked by inter-molecular N-H⋯O hydrogen bonds from the 2-amino-phenyl group. In addition there are inter-molecular N-H⋯O hydrogen bonds between the amine and carbonyl groups of adjacent mol-ecules. The mol-ecule is twisted rather than planar due to a steric inter-action between the central amide group and the two outer benzene rings. The dihedral angles between this central group and the two rings are 23.29 (9) and 24.96 (9)°.

In the title mol-ecule, C(15)H(13)ClN(2)O, the two benzene rings form a dihedral angle of 5.48 (4)°. In the crystal, N-H⋯O hydrogen bonds link mol-ecules related by translation along the a axis into chains, which are further aggregated into layers parallel to the ac plane through weak C-H⋯O and C-H⋯N inter-actions.
