要旨:
In the title hydrazide Schiff base compound, C14H12ClN3O2, the conformation around the C=N double bond is E. The dihedral angle between the benzene rings is 41.57 (14) Å. An intramolecular O-H...N hydrogen bond makes an S(6) ring motif. In the crystal, molecules are linked by N-H...O (bifurcated acceptor) and N-H...N hydrogen bonds, forming chains along the a axis. The interesting feature of the crystal structure is the short intermolecular C...O [3.216 (3), 3.170 (3), and 2.992 (3) Å] contacts, one of which is significantly shorter than the sum of the van der Waals radii of these atoms [3.22 Å].
