In the title compound, C9H10N2O3, the hydroxy group and the C=N—N unit are coplanar with the benzene ring. The benzene rings of inversion-related molecules are stacked with their centroids separated by a distance of 3.7703 (9) Å, indicating weak π–π interactions. In the C—H⋯O, O—H⋯O, N—H⋯O and C—H⋯O hydrogen bonds link molecules into a infinite two-dimensional network along the a axis.

4-Hydroxy benzaldehyde (12.2 g, 0.1 mol) and methyl hydrazinecarboxylate (9.0 g, 0.1 mol) were dissolved in methanol (50 ml) solution and stirred for 6 h at room temperature. The resulting solid was filtered off and recrystallized from an ethanol solution to give (I) in 80% yield. Crystals suitable for X-ray analysis were obtained by the slow evaporation of an ethanol solution held at room temperature (m.p. 475–478 K).
The H atoms were included in the riding model approximation with O—H = 0.84 Å, N—H = 0.86 Å and C—H = 0.95 - 0.98 Å, and with Uiso(H) = 1.2Ueq(C, N) and 1.5Ueq(O, 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. |

Benzaldehydehydrazone derivatives have received considerable attention owing to their pharmacological activity (Parashar et al., 1988) and their photochromic properties (Hadjoudis et al., 1987). In addition, they are important intermediates in the synthesis of 1,3,4-oxadiazoles, which have been reported to be versatile compounds (Borg et al., 1999). As a part of an investigation of this type of derivative, the crystal structure of the title compound, C9H10N2O3 (I), is described herein.
In (I), Fig. 1 & Table 1, all non-hydrogen atoms are co-planar to within ±0.699 (4) Å. The molecule is in the E-conformation with respect to the N=C double bond. The bond lengths and angles defining the C=N—N(H)—C group are close to those of the previously reported N'-(4-Methoxybenzylidene)methoxyformohydrazide structure (shang et al., 2007).
The benzene rings of inversion-related molecules are stacked with their centroids separated by a distance of 3.7703 (9) Å, consistent with π-π interactions.
