(E)-N'-(3-Hy-droxy-benzyl-idene)-3-nitro-benzohydrazide.

ABSTRACT

The title compound, C(14)H(11)N(3)O(4), was prepared by the reaction of 3-nitro-benzohydrazide with 3-hy-droxy-benzalde-hyde. The mol-ecule adopts an E configuration about the C=N bond. The dihedral angle between the two benzene rings is 32.3 (2)°. In the crystal, the mol-ecules are linked through inter-molecular N-H⋯O, O-H⋯N, and O-H⋯O hydrogen bonds, forming chains in the a-axis direction.
