(Received 27 July 2008; accepted 30 July 2008; online 13 August 2008)

The mol­ecule of the title compound, C10H12N2O3, adopts a trans configuration with respect to the C=N bond. The dihedral angle between the benzene ring and the hydrazinecarboxyl­ate plane is 8.98 (7)°. Intra­molecular O—H⋯N and C—H⋯N hydrogen bonds are observed. Mol­ecules are linked into chains along the c axis by N—H⋯O hydrogen bonds. In addition, C—H⋯π inter­actions are observed.

Comment top

Benzaldehydehydrazone compounds have received considerable attention for a long time due to their pharmacological activity (Parashar et al., 1988) and their photochromic properties (Hadjoudis et al., 1987). They are important intermediates 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 derivatives, the crystal structure of the title compound is reported here.

The title molecule (Fig.1) adopts a trans configuration with respect to the CN bond. The C9/C10/N1/N2/O2/O3 plane of 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 C9/C10/N1/N2/O2/O3 plane is 8.98 (7)°. The bond lengths and angles agree with those observed for methyl N'-((E)-1-phenylethylidene)hydrazinecarboxylate (Cheng, 2008). Intramolecular O—H···N and C—H···N hydrogen bonds are observed.

The molecules are linked into chains along the c axis by N—H···O hydrogen bonds. In addition, C—H···π interactions are observed (Table 1, Fig.2).

Experimental top

2-Hydroxyacetophenone (1.36 g, 0.01 mol) and methyl hydrazinecarboxylate (0.9 g, 0.01 mol) were dissolved in stirred methanol (15 ml) and left for 2 h at room temperature. The resulting solid was filtered off and recrystallized from ethanol to give the title compound in 85% yield. Single crystals suitable for X-ray analysis were obtained by slow evaporation of an ethanol solution at room temperature (m.p. 465–467 K).

Refinement top

H atoms were positioned geometrically (O-H = 0.82 Å, N-H = 0.86 Å and C-H = 0.93 or 0.96 Å) and refined using a riding model, with Uiso(H) = 1.2–1.5Ueq(C). A rotating group model was used for the methyl groups.

Special details top

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.
