چکیده
Crystals of the title compound, C(15)H(15)N(3)O, were obtained from a condensation reaction of benzohydrazide and 1-(4-amino-phen-yl)ethanone. The mol-ecule assumes an E configuration with the amino-phenyl and benzohydrazide units located on opposite sites of the C=N double bond. In the crystal structure, the benzene rings of the mol-ecule are slightly twisted with respect to the central hydrazide, the dihedral angles being 18.22 (12) and 27.62 (12)°. The crystal structure contains inter-molecular N-H⋯O and weak C-H⋯N hydrogen bonding.
