2-Methyl-N'-(4-nitrobenzylidene)benzohydrazide

C.-B. Tang

Abstract top

The title hydrazone compound, C15H13N3O3, was prepared by the condensation of 4-nitrobenzaldehyde with 2-methylbenzohydrazide in methanol. The dihedral angle between the two benzene rings is 14.8 (2)°. In the crystal, molecules are linked through intermolecular N-H...O hydrogen bonds, forming chains along the a axis.

Comment top

Hydrazone compounds have received much attention in biological chemistry and structural chemistry in the last few years (Rasras et al., 2010; Pyta et al., 2010; Angelusiu et al., 2010; Fun et al., 2008; Singh & Singh, 2010; Ahmad et al., 2010). In the present paper, the author reports the crystal structure of the title new hydrazone compound (Fig. 1).

In the title molecule, the dihedral angle between the two benzene rings is 14.8 (2)°. The torsion angles C4—C7—N2—N3, C7—N2—N3—C8 and N2—N3—C8—C9 are 3.9 (2), 13.8 (2), and 1.5 (2)°, respectively. All the bond lengths are within normal values (Allen et al., 1987) and comparable with those of a similar hydrazone compound the author reported recently (Tang, 2010).

In the crystal structure of the compound, molecules are linked through N–H···O intermolecular hydrogen bonds (Table 1), forming chains along the a axis (Fig. 2).

Experimental top

4-Nitrobenzaldehyde (0.1 mmol, 15.1 mg) and 3-methylbenzohydrazide (0.1 mmol, 15.0 mg) were dissolved in methanol (20 ml). The mixture was stirred at reflux for 10 min to give a clear yellow solution. Yellow block-shaped crystals of the title compound were formed by slow evaporation of the solvent over several days.

Refinement top

Atom H3 was located in a difference Fourier map and refined isotropically, with the N–H distance restrained to 0.90 (1) Å [Uiso(H) = 0.08 Å2]. Other H atoms were constrained to ideal geometries, with C–H = 0.93–0.96 Å, and with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C) for methyl H atoms.

Special details top

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.
