(E)-4-Hydroxy-N′-(4-nitrobenzylidene)benzohydrazide

The molecule of the title compound, C(14)H(11)N(3)O(4), is approximately planar, the dihedral angle between the planes of the two substituted benzene rings being 2.54 (7)degrees. The molecule exists in a trans configuration with respect to the central methylidene unit. In the crystal structure, molecules are linked through intermolecular O-H center dot center dot center dot O, N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds, forming layers parallel to (101). The O/N-H center dot center dot center dot O and C-H center dot center dot center dot O interactions form a pair of bifurcated acceptor bonds involving the cabonyl/nitro O atom, generating an R(2)(1)(6) motif.
