N′-(4-Fluorobenzylidene)-2-(4-fluorophenyl)acetohydrazide

In the title compound, C15H12F2N2O, the dihedral angle between the two benzene rings is 48.73 (8)°. The hydrazine group is twisted slightly, with a C—N—N—C torsion angle of 172.48 (12)°. In the crystal, molecules are connected by strong N—H...O and weak C—H...O hydrogen bonds, forming supramolecular chains along the c axis. The structure is consolidated by π–π [centroid–centroid separation = 3.6579 (10) Å] and C—H...π interactions
