In the title molecule, C9H10N2O3, the hydrazinecarboxylic acid mean plane and the benzene ring form a dihedral angle of 11.1 (1)°. In the intermolecular N—H⋯O hydrogen bonds link the molecules into chains extending along the b axis. An intramolecular O—H⋯N hydrogen bond is also present.

2-hydroxy benzaldehyde (1.22 g, 0.01 mol) and methyl hydrazinecarboxylate (0.90 g, 0.01 mol) were dissolved in stirred methanol (20 ml) and left for 3 h at room temperature. The resulting solid was filtered off and recrystallized from ethanol to give the title compound in 90% yield. Crystals suitable for X-ray analysis were obtained by slow evaporation of a ethanol solution at room temperature (m.p. 465–468 K).
All H atoms were positioned geometrically (N—H 0.88 Å, O—H 0.84 Å, C—H 0.95-0.98 Å) and refined in the riding model approximation,, with Uiso(H) = 1.2–1.5Ueq of the parent atom.

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 attentions for a long time due to their pharmacological activity (Parashar et al., 1988) and their photochromic properties (Hadjoudis et al., 1987). Meanwhile, it's an important intermidiate of 1,3,4-oxadiazoles, which have been reported to be versatile compounds with many useful properties (Borg et al., 1999). As a further investigation of this type of derivatives, the crystal structure of the title compound, C9H10N2O3, is described here.
The title molecule (Fig. 1) adopts a trans configuration with respect to the C=N bond. Intramolecular O—H···N hydrogen bond (Table 1) influences the molecular conformation. The hydrazine carboxylic acid methyl ester group is slightly twisted away from the attached ring. The dihedral angle between the C1-C6 ring and the C8/C9/N1/N2/O2/O3 plane is 11.1 (1)°. The bond lengths and angles agree with those observed for (E)-Methyl N'-(4-hydroxybenzylidene) hydrazinecarboxylate (Cheng, 2008).
In the crystal, intermolecular N–H···O (Table 1) hydrogen bonds link the molecules into chains extended along b axis.
