The title compound was prepared by refluxing 4-nitrobenzaldehyde (1.0 mol) with 4-methoxybenzohydrazide (1.0 mol) in methanol (100 ml). Excess methanol was removed from the mixture by distillation. A colourless solid product was filtered, and washed three times with methanol. Colourless block-shaped crystals of the title compound were obtained from a methanol solution by slow evaporation in air.
Atom H3A was located in a difference Fourier map and refined isotropically, with the N—H distance restrained to 0.90 (1)Å and Uiso fixed at 0.08 Å2. The remaining H atoms were placed in calculated positions (C—H = 0.93–0.96 Å and O—H = 0.82 Å) and refined as riding with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(O and methyl C).
Hydrazone compounds derived from the condensation of
with have been demonstrated to possess excellent biological activities (Zhong et al., 2007; Raj et al., 2007; Jimenez-Pulido et al., 2008). Due to the easy synthesis of such compounds, a large number of hydrazone compounds have been synthesized and structurally characterized (Yehye et al., 2008; Fun, Patil, Jebas et al., 2008; Fun, Patil, Rao et al., 2008; Yang et al., 2008; Ejsmont et al., 2008). Recently, we have reported a few such compounds (Ban & Li, 2008a,b; Li & Ban, 2009a,b). Herein the of the title new compound is reported.The

The molecule exists in a trans configuration with respect to the central methylidene unit. In the the hydrazone molecules and the methanol molecules are linked through intermolecular O—H···O, O—H···N and N—H···O hydrogen bonds (Table 1), forming chains along the a axis (Fig. 2).For the biological activity of

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. |

Hydrazone compounds derived from the condensation of aldehydes with hydrazides have been demonstrated to possess excellent biological activities (Zhong et al., 2007; Raj et al., 2007; Jimenez-Pulido et al., 2008). Due to the easy synthesis of such compounds, a large number of hydrazone compounds have been synthesized and structurally characterized (Yehye et al., 2008; Fun, Patil, Jebas et al., 2008; Fun, Patil, Rao et al., 2008; Yang et al., 2008; Ejsmont et al., 2008). Recently, we have reported a few such compounds (Ban & Li, 2008a,b; Li & Ban, 2009a,b). Herein the crystal structure of the title new compound is reported.
The asymmetric unit of the title compound consists of a hydrazone molecule and a methanol molecule (Fig. 1). The hydrazone molecule is nearly planar, the dihedral angle between the two benzene rings being 1.2 (4)°. The molecule exists in a trans configuration with respect to the central methylidene unit. In the crystal structure, the hydrazone molecules and the methanol molecules are linked through intermolecular O—H···O, O—H···N and N—H···O hydrogen bonds (Table 1), forming chains along the a axis (Fig. 2).
