A mixture of 3-methoxy-5-nitrosalicylaldehyde (0.197 g, 1 mmol) and 2-hydroxy-3-methylbenzohydrazide (0.166 g, 1 mmol) in 50 ml methanol was stirred at room temperature for 1 h. The mixture was filtered to remove impurities, and then left at room temperature. After a few days, single crystals of the title compound, suitable for X-ray diffraction, were formed.
Amino H atom was located from a difference Fourier map and refined isotropically, with N—H distance restrained to 0.90 (1) Å. Other H atoms were positioned geometrically and refined using the riding-model approximation, with C—H = 0.93 or 0.96 Å, O—H = 0.82 Å, and Uiso(H) = 1.2Ueq(C) or Uiso(H) = 1.5Ueq(methyl C and O).
Hydrazone compounds have been widely investigated for their biological properties (Patil et al., 2010; Cukurovali et al., 2006). Furthermore, the crystal structures of the hydrazone compounds have also attracted much attention in recent years (Mohd Lair et al., 2009; Lin & Sang, 2009; Suleiman Gwaram et al., 2010). As a continuous work on the structural characterization of such compounds (Han & Zhao, 2010a,b), the title new hydrazone compound is reported.
In the title compound, Fig. 1, the dihedral angle between the two benzene rings is 0.9 (2)°. The molecule adopts an E configuration with respect to the C═N bond. There are intramolecular O—H···N and O—H···O hydrogen bonds in the molecule (Table 1). All the bond lengths are within normal ranges (Allen et al., 1987), and are comparable with those in the similar compounds (Li & Ban, 2009; Lo & Ng, 2009; Ning & Xu, 2009; Zhu et al., 2009).

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 > 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 have been widely investigated for their biological properties (Patil et al., 2010; Cukurovali et al., 2006). Furthermore, the crystal structures of the hydrazone compounds have also attracted much attention in recent years (Mohd Lair et al., 2009; Lin & Sang, 2009; Suleiman Gwaram et al., 2010). As a continuous work on the structural characterization of such compounds (Han & Zhao, 2010a,b), the title new hydrazone compound is reported.
In the title compound, Fig. 1, the dihedral angle between the two benzene rings is 0.9 (2)°. The molecule adopts an E configuration with respect to the C═N bond. There are intramolecular O—H···N and O—H···O hydrogen bonds in the molecule (Table 1). All the bond lengths are within normal ranges (Allen et al., 1987), and are comparable with those in the similar compounds (Li & Ban, 2009; Lo & Ng, 2009; Ning & Xu, 2009; Zhu et al., 2009).
In the crystal structure, molecules are linked through intermolecular N—H···O hydrogen bonds (Table 1) to form chains running along the c axis (Fig. 2).
