In the title compound, C17H14N2O, the N-benzyl­formamide and phenyl groups are located on the opposite sides of the C=C bond, showing an E configuration; the terminal phenyl rings are twisted to each other at a dihedral angle of 63.61 (7)°. Inter­molecular classical N—H⋯N and weak C—H⋯O hydrogen bonds occur in the crystal structure.

Comment top

The phenylacrylamide derivatives have broad application for the preparation of heterocyclic ring compounds. The phenylacrylamide derivatives was studied extensively, Rajan (Rajan et al.,2001) synthesized a series of phenylacrylamide derivatives and evaluated their antioxidant properties as lipid peroxidation inhibitors. Some phenylacrylamide derivatives and analogues were synthesized and studied antibacterial activity against S. aureus (Yingyongnarongkul et al.,2006). Some phenylacrylamide derivatives were synthesized for the purpose of simplifying the structure of L-chicoric acid as new HIV-1 integrase inhibitors (Lee et al., 2002).As an extension of this research, we report the synthesis and the crystal structure of the title compound (I), namely, (E)—N-benzyl-2-cyano-3-phenylacrylamide.

The molecular structure of (I) is shown in Fig. 1. Bond lengths and angles in (I) are normal. The dihedral angle between the C1—C6 and C12—C17 benzene planes is 63.62 (5)°. The crystal packing is stabilized by N—H···N an C—H···O hydrogen bonding (Table 1).

Experimental top

N-Benzyl-2-cyanoacetamide (0.258 g, 2 mmol) and benzaldehyde (0.212 g, 2 mmol) were dissolved in 2-propanol (2 ml). To the solution was added piperidine (0.017 g, 0.2 mmol),the solution was stirred for 24 h at 273 K and the solution was filtered to obtain a solid. Recrystallization from hot ethanol afforded the pure compound. Single crystals of (I) suitable for X-ray analysis were obtained by slow evaporation ethanol solvent.

Refinement top

Imino H atom was located in a difference Fourier map and refined isotropically. Other H atoms were placed in calculated positions, with C—H = 0.93–0.97 Å, and refined using a riding model, with Uiso(H) = 1.2Ueq(C).

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.
