2-Chloro-5-nitrobenzaldehyde (1.0 mmol, 185 mg) and 2-nitrobenzohydrazide (1.0 mmol, 181 mg) were mixed in 50 mL methanol. The mixture was stirred at ambient temperature for 2 h and filtered. Colorless blocks of (I) were formed by slow evaporation of the filtrate for 5 d.
The amino hydrogen atom was located in an electronic density map and refined isotropically, with the N—H distance restrained to 0.90 (1)Å. Other hydrogen atoms were placed in calculated positions, with C—H = 0.93 Å, and refined as riding with Uiso(H) = 1.2Ueq(C). The structure contains solvent accessible VOIDS of 70 Å3, which might accord a disordered water molecule.
Recently, the author has reported a hydrazone compound (Liu, 2010). As a further study on these compounds, in the present work, a new hydrazone compound is reported.
In the title compound (Fig. 1), the hydrazone molecule exists in a trans geometry with respect to the methylidene unit. The dihedral angle between the two substituted benzene rings is 62.7 (2)°. The O1/N3/O2 nitro plane forms a dihedral angle of 3.7 (2)° with the C1-C6 benzene ring. The O4/N4/O5 nitro plane forms a dihedral angle of 33.9 (2)° with the C9-C14 benzene ring. In the
adjacent two molecules are linked through two N—H···O hydrogen bonds (Table 1) to form a dimer (Fig. 2).For a related structure and background references, see: Liu (2010).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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. |

Recently, the author has reported a hydrazone compound (Liu, 2010). As a further study on these compounds, in the present work, a new hydrazone compound is reported.
In the title compound (Fig. 1), the hydrazone molecule exists in a trans geometry with respect to the methylidene unit. The dihedral angle between the two substituted benzene rings is 62.7 (2)°. The O1/N3/O2 nitro plane forms a dihedral angle of 3.7 (2)° with the C1-C6 benzene ring. The O4/N4/O5 nitro plane forms a dihedral angle of 33.9 (2)° with the C9-C14 benzene ring. In the crystal structure, adjacent two molecules are linked through two N—H···O hydrogen bonds (Table 1) to form a dimer (Fig. 2).
