The title compound, C14H10N4O5, has an E conformation with respect to the C=N bond. The dihedral angle between the benzene rings is 2.41 (14)°. In the crystal, molecules are linked through N—H⋯O hydrogen bonds to form chains along the c axis. C—H⋯O interactions are also present, linking the chains to form a three-dimensional network.

A mixture of 3-nitrobenzaldehyde (0.151 g, 1 mmol) and 4-nitrobenzohydrazide (0.181 g, 1 mmol) in 30 ml of ethanol containing few drops of acetic acid was refluxed for about 1 h. On cooling to room temperature, a solid precipitate was formed. The solid was filtered and then recrystallized from methanol. Yellow crystals, suitable for X-ray
were obtained by slow evaporation of a solution of the title compound in methanol.The amino H atom was located from a difference Fourier map and was freely refined. The remaining H-atoms were included in calculated positions and refined using a riding model: C–H = 0.93 Å, with Uiso(H) = 1.2Ueq(C).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

In recent years, hydrazone compounds have attracted much attention due to their syntheses and crystal structures (Hashemian et al., 2011; Lei, 2011; Shalash et al., 2010). As a continuation of our work on such compounds (Li, 2011a,b; Li, 2012), the author reports herein on the crystal structure of the new title hydrazone compound.
The title compound (Fig. 1) exists in an E conformation with respect to the C7═N1 bond. The dihedral angle between the (C1–C6) and (C9–C14) benzene rings is 2.41 (14) °.
In the crystal, molecules are linked through N–H···O hydrogen bonds to form chains along the c axis (Fig. 2 and Table 1). There are also C-H···O interactions present that link the chains to form a three-dimensional network (Table 1).
