The title compound, C13H16N2O3, adopts an E configuration with respect to the C=N bond and an intramolecular N—H⋯N hydrogen bond results in the formation of a six-membered ring. In the crystal, intermolecular O—H⋯O hydrogen bonds link the molecules into a chain propagating along the b axis. Very weak π–π stacking interactions [centroid–centroid distance = 4.18 (2) Å] may further consolidate the packing, forming a two-dimensional supramolecular network.

To a solution of 1-acetyl-N-(2-methoxyphenyl)cyclopropanecarboxamide (2.33 g, 10 mmol) and NaOAc (1.64 g, 20 mmol) in EtOH (25 ml) and H2O (1 ml) was added NH2OH.HCl (1.39 g, 20 mmol) in one portion. The reaction mixture was stirred at room temperature for 12 h, and then poured into ice-water (200 ml) under stirring. A white solid was precipitated, which was filtered and the residue was purified by a flash silica gel
to give colourless blocks of (I) (eluent: ether/ethyl acetate = 1/3 v/v).The N- and O-bound H atoms were located in a difference map and their positions were freely refined. The C-bound H atoms were geometrically placed (C—H = 0.93–0.97Å) and refined as riding. The constraints Uiso = 1.2Ueq(C,N) or 1.5Ueq(methyl C,O) were applied.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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. |

Cyclopropane and their derivatives are a significant class of compounds which can be used in a variety of studies such as organic synthesis, catalytic reaction and so on (Liu & Montgomery, 2006; Ogoshi et al., 2006). In order to extend our work on structural characterization of cyclopropane compounds, we report the synthesis and the X-ray structure of the title compound, (I), in this paper (Fig. 1).
The title molecule adopts an E configuration with respect to C=N bond. There is an intramolecular O—H···N hydrogen bonds, forming of a six-membered ring (Table 1) and the intermolecular O—H···O hydrogen bonds link the molecules into a one-dimensional chain along the b axis. The crystal structure is further stabilized by π-π interaction involving the benzene rings: Cg1···Cg1 (1 - x, 1 - y, 1 - z) = 4.18 (2) Å, where Cg1 denotes the centroid of the C2—C7 (Fig. 2).
