The title molecule, C12H16N2O5, adopts a trans configuration with respect to the C=N bond. In the crystal, intermolecular N—H⋯O hydrogen bonds link the molecules into chains in [001], and weak intermolecular C—H⋯O interactions further link the chains into corrugated layers parallel to the bc plane.

2,4,5-Trimethoxybenzaldehyde (1.96g, 0.01mol) and methyl hydrazinecarboxylate (0.9g, 0.01mol) were dissolved in stirred methanol (20ml) and left for 5.2h at room temperature. The resulting solid was filtered off and recrystallized from ethanol to give the title compound in 91% yield. Crystals suitable for X-ray analysis were obtained by slow evaporation of a ethanol solution at room temperature (m.p. 432-435 K).
H atoms were geometrically positioned (C—H 0.93 - 0.96 Å; N—H 0.86 Å), and refined using a riding model, with Uiso(H) = 1.2-1.5 Ueq(C, N).

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 > 2sigma(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 due to their pharmacological activity (Parashar et al., 1988) and photochromic properties (Hadjoudis et al., 1987). They also serve as intermidiates of 1,3,4-oxadiazoles, which have been reported to be versatile compounds with many properties (Borg et al., 1999). As a further investigation of this type of compounds, we report herein the crystal structure of the title compound (I).
The title compound (Fig.1) adopts a trans configuration with respect to the C═N bond. The hydrazine carboxylic acid methyl ester group is slightly twisted away from the attached ring. The dihedral angle between the benzene ring and the C10/C11/C12//N1/N2/O4/O5 plane is 14.23 (5)°. The bond lengths and angles agree with those observed for (E)-methyl N'-(4-hydroxybenzylidene)hydrazinecarboxylate (Shang et al., 2007).
In the crystal structure, intermolecular N—H···O hydrogen bonds (Table 1) link molecules into chains in [001], and weak intermolecular C—H···O interactions (Table 1) link further these chains into corrugated layers parallel to bc plane.
