4-Nitrophenylhydrazine (1 mmol, 0.153 g) was dissolved in anhydrous methanol and H2SO4 (98% 0.5 ml) was added. The resultant solution was stirred for several minutes at 351 K. Cinnamaldehyde (1 mmol 0.132 g) in methanol (8 ml) was added dropwise and the mixture was stirred at refluxing temperature for 2 h. The product was isolated and recrystallized in dichloromethane. Brown single crystals of (I) were obtained after 6 d.
All H atoms were placed in calculated positions, with C—H = 0.93Å (aromatic) with Uiso(H) = 1.2Ueq(C). H2A was located from a difference Fourier map and refined isotropically, with N–H distance restrained to 0.89 (3)Å.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
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. |

4-Nitrophenylhydrazine has applications in organic synthesis and some of its derivatives have been shown to be potentially DNA-damaging and mutagenic agents (Okabe et al., 1993). As part of our interest in the study of the coordination chemistry, we report the synthesis and crystal structure of the title compound (I).
The 4-nitrophenyl group and the benzene ring are slightly twisted, making a dihedral angle of 9.1 (2)°. The dihedral angle between the N1/O1/O2 and its attached benzene ring is 7.4 (2)° (Fig. 1).
The molecules are linked by N—H···O hydrogen bonds to form a zigzag like chain (Fig. 2).
