The molecule of the title compound, C10H12N2O4, adopts a trans configuration with respect to the C=N double bond. The dihedral angle between the benzene ring and the hydrazinecarboxylate mean plane is 36.54 (6)°. The molecules are linked into a two-dimensional network by intermolecular O—H⋯O, N—H⋯O and O—H⋯N hydrogen bonds, and by aromatic π–π stacking interactions [ring-centroid separation 3.7689 (9) Å].

4-Hydroxy-3-methoxybenzaldehyde (1.52 g, 0.01 mol) and methyl hydrazinecarboxylate (0.9 g, 0.01 mol) were dissolved in stirred methanol (15 ml) and left for 2.5 h at room temperature. The resulting solid was filtered off and recrystallized from ethanol to give the title compound in 90% yield. Colourless blocks of (I) were obtained by slow evaporation of a ethanol solution at room temperature (m.p. 480–482 K).
The H atoms were placed geometrically (O—H = 0.84 Å, N—H = 0.88 Å and C—H = 0.95 or 0.98 Å) and refined as riding, with Uiso(H) = 1.2 or 1.5Ueq(carrier).

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. |

As part of our ongoig studies of benzaldehydehydrazone derivatives (Cheng, 2008), we now report the synthesis and structure of the title compound, (I).
The title molecule (Fig. 1) adopts a trans configuration with respect to the C═N bond. The dihedral angle between the benzene ring and the C9/C10//N1/N2/O3/O4 plane is 36.54 (6)°. Otherwise, the bond lengths and angles for (I) agree with those observed for (E)-methylN'-(4-hydroxybenzylidene)hydrazinecarboxylate (Cheng, 2008).
In the crystal, the molecules are linked into a two-dimensional network by intramolecular O—H···O and intermolecular O—H···O, N—H···O, O—H···N hydrogen bonds (Table 1). Additionally, neighbouring aromatic rings interact by π–π stacking [centroid separation = 3.7689 (9) Å].
