In the title compound, C₈H₁₀N₂O₂, the acetohydrazide group is almost planar, with an r.m.s. deviation of 0.028 Å. In the crystal, the molecules are linked by intermolecular C—H⋯O, N—H⋯O and N—H⋯N hydrogen bonds into infinite sheets lying parallel to (001). The acetohydrazide O atom accepts two N—H⋯O links and one C—H⋯O link.

Comment top

Hydrazine derivatives have been reported to possess several biological properties. 5-nitro-2-heterocyclic benzylidine hydrazides were found to possess antileishmanial activities (Rando et al., 2008). Many substituted benzoic acid furan-2-yl-methylene hydrazides showed potent antimicrobial properties (Kumar et al., 2009). Hydrazine derivatives were also associated with remarkable anticancer (Kamal et al., 2007), antibacterial (Masunari & Tavares, 2007) and tuberculostatic (Rando et al., 2002) activities.

The molecular structure is shown in Fig. 1. The acetohydrazide group (C7/C8/N1/N2/O2) is almost planar, with an r.m.s. deviation of 0.028 Å. Bond lengths and angles are within normal ranges, and comparable to a closely related structure (Fun et al., 2009). In the crystal packing (Fig. 2), the molecules are linked via intermolecular C1—H1A···O2, N2—H1N2···O2 and N2—H2N2···O2 trifurcated acceptor bonds, together with N1—H1N1···N2 hydrogen bonds, into infinite two-dimensional networks parallel to plane (0 0 1).

Experimental top

Phenol (11 ml, 1.20 mmol), ethyl chloroacetate (12.8 ml, 1.20 mmol) and potassium carbonate (20.75 g, 1.50 mmol) were refluxed in acetone (100 ml) at 80 °C for 18 h. The reaction mixture was then filtered, distilled to remove the acetone and poured into ice cold water with vigorous stirring. The ester, phenoxy ethyl acetate was extracted using ether. The solution was distilled to remove ether. Phenoxy ethyl acetate (8.2 ml, 0.50 mmol) was heated at 100 °C for 10h in absolute alcohol medium (40 ml) with hydrazine hydrate (2.5 ml, 0.50 mmol). The reaction mixture was allowed to cool, the solid separated was filtered, dried and recrystallized from ethanol. The yield was found to be 5.7 g (69 %). M. p. 381-383 K (Holla & Udupa, 1992).

Special details top

Experimental. The crystal was placed in the cold stream of an Oxford Cyrosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

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.
