Comment top

Schiff bases are a kind of interesting compounds, which possess excellent biological properties, such as antibacterial, antimicrobial, and antitumor (Mohamed et al., 2009; Ritter et al., 2009; Bagihalli et al., 2008). Recently, a large number of Schiff bases derived from the reaction of aldehydes with benzohydrazides have been reported (Fun et al., 2008; Shafiq et al., 2009; Goh et al., 2010). In this paper, the crystal structure of the title new Schiff base compound is reported.

In the title compound (Fig. 1), bond lengths are comparable with those observed in related structures (Zhou et al., 2009; Zhou & Yang, 2009). The molecule exists in a trans configuration with respect to the acyclic CN bond. The molecule is distorted from planarity, with a dihedral angle between the two benzene rings of 15.9 (2)°.

In the crystal structure, intermolecular N—H···O hydrogen bonds link adjacent molecules into chains along the [101] (Table 1 and Fig. 2).

Experimental top

4-Nitrobenzaldehyde (1.0 mmol, 151.0 mg) and 2-chlorobenzohydrazide (1.0 mmol, 170.0 mg) were dissolved in methanol (30 ml). The mixture was stirred for 30 min at room temperature. The resulting solution was left in air for a few days, yielding colourless block-shaped crystals.

Refinement top

Atom H2A was located in a difference map and refined with a N–H distance restraint of 0.90 (1) Å and Uiso(H) = 0.08 Å2. The remaining H atoms were positioned geometrically (C–H = 0.93 Å) and refined using a riding model, with Uiso(H) = 1.2Ueq(C).

Special details top

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.
