The title compound, C15H13N3O4·CH4O, was synthesized from the reaction of 4-methoxybenzaldehyde with 4-nitrobenzohydrazide in methanol. The benzene rings of the Schiff base molecule are nearly coplanar, making a dihedral angle of 7.0 (3)°. The methanol solvent molecules are linked to the Schiff base molecules by N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds, forming chains running parallel to the b axis.

4-Methoxybenzaldehyde (0.1 mmol, 13.6 mg) and 4-nitrobenzohydrazide (0.1 mmol, 18.1 mg) were dissolved in methanol (20 ml). The mixture was stirred at reflux for 1 h and cooled to room temperature. After keeping the solution in air for five days, yellow block-like crystals were formed on slow evaporation of the solvent.
H2A was located from a difference Fourier map and refined isotropically, with the N–H distance restrained to 0.90 (1) Å. Other H atoms were placed in calculated positions and constrained to ride on their parent atoms, with C–H distances of 0.93–0.96 Å, O–H distance of 0.82 Å, and with Uiso(H) = 1.2Ueq(C) and 1.5Ueq(O and methyl C).

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. |

Schiff base compounds have been found to have potential pharmacological and antitumor properties (Brückner et al., 2000; Harrop et al., 2003; Ren et al., 2002). Recently, a few Schiff base compounds derived from the reaction of aldehydes with benzohydrazides have been reported (Diao et al., 2008; Diao et al., 2007; Diao, 2007; Li et al., 2007; Huang et al., 2007). As a further study of such compounds, we report here the structure of the title compound.
The title compound (Fig. 1) consists of a Schiff base molecule and a lattice methanol molecule. The Schiff base molecule is nearly planar with the dihedral angle between the two phenyl rings of 7.0 (3)°. The dihedral angle between the C1—C6 phenyl ring and the O1/N1/O2 nitryl plane is 5.1 (3)°. The torsion angles C9—C8—N3—N2 and C4—C7—N2—N3 are 1.4 (3) and 1.6 (3)°, respectively. The methanol molecules are linked to the Schiff base molecules by N–H···O, O–H···N and O–H···O hydrogen bonds (Table 1) forming chains running parallel to the b axis.
