چکیده
The title compound, C(14)H(10)ClN(3)O(4), was synthesized by the reaction of 5-hydr-oxy-2-nitro-benzaldehyde with an equimolar quantity of 4-chloro-benzohydrazide in methanol. The mol-ecule displays an E configuration about the C=N bond. The dihedral angle between the two benzene rings is 3.9 (2)°. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, forming chains running along the b axis.
