چکیده
The title hydrazone compound, C(14)H(10)Cl(2)N(2)O(2), was synthesized by the reaction of 2,4-dichloro-benzaldehyde and 4-hy-droxy-benzohydrazide. The mol-ecule adopts an E geometry with respect to the azomethine group and the dihedral angle between the aromatic rings is 7.0 (2)°. In the crystal, mol-ecules are linked through inter-molecular N-H⋯Cl and O-H⋯O hydrogen bonds, forming a three-dimensional network.
