The title compound, C9H9NO, crystallized with two independent molecules (A and B) in the The conformation of the two molecules differs slightly with the phenyl ring in molecule A, forming a dihedral angle of 15.38 (12)° with the oxime group (O—N=C), compared to the corresponding angle of 26.29 (11)° in molecule B. In the crystal, the A and B molecules are linked head-to-head by O—H⋯N hydrogen bonds, forming –A–B–A–B– zigzag chains along [010]. Within the chains and between neighbouring chains there are C—H⋯π interactions present, forming a three-dimensional structure.

Many uses of cinnamaldehyde oxime have been reported, such as the conversion to cinnamonitrile (Narsaiah & Nagaiah 2004; Jasem et al. 2014), conversion to cinnamide (Garton et al. 2010), and as a starting material for N-heterocycles: tetrazole (Patil et al. 2012), isoxazoline (Kaur et al. 2006), and izoxazoline (Boruah & Konwar 2012).

(Fig. 1). The aromatic ring in molecule A (C1A—C6A) forms a dihedral angle of 15.38 (12)° with the oxime group (C9A/N1A/O1A), compared to a corresponding angle of 26.29 (11)° in molecule B. This conformational difference between molecules A and B is due to bond rotation, not only about bonds (C1—C7) and (C8—C9) but also of that of (C7—C8), where in molecule A the torsion angle C1—C7—C8—C9 is -174.32 (11)° while in molecule B the corresponding angle is -179.24 (11) °. The bond lengths, C7—C8, of molecules A and B are similar.In the crystal, the A molecules align opposite B molecules, and they are linked via O—H···N hydrogen bonds forming -A—B—A—B- zigzag chains propagating along the b axis (Table 1 and Fig. 2). Adjacent molecules of the same type are tilted against each other, with the aromatic rings (C1—C6) being inclined to one another by 77.64 (2) and 59.04 (2)° for molecules A and B, respectively. In addition, adjacent molecules of the same type exhibit weak C—H..π (C2A—H2A···Cg1 and C5B—H5B···Cg2) contacts along the b axis direction (Table 1 and Fig. 2). Along the c axis, inversion related dimers stack with an offset of 11.47 (2) Å and connected via a weak C—H..π (C9B—H9B···Cg2) contact (Fig. 3 and Table 1).
To a solution of cinnamaldehyde (1.32 g, 10 mmol) in ethanol (20 ml) was added drop wise a solution of hydroxylamine hydrochloride (2.74 g, 39.7 mmol) in water (7.5 ml), and the resulting mixture was stirred at 60 oC for 3 h. Thereafter, about half of the solvent was removed in vacuo, and the remaining reaction mixture was poured into water (50 ml) and extracted with CHCl3 (3 × 20 ml).

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. |
