Comment top

The title compound, (I), is found to be of interest as an organic non-linear optical (NLO) material. The crystals show optical second harmonic generation with the fundamental beam (λ = 1064 nm) of Nd–YAG laser. The single-crystal structure elucidation further reinforces this observation.

Fig. 1 shows the title compound. The torsion angles about the C(phenyl)—N(amide) and C(phenyl)-N–(nitro) bonds shows that the amide and nitro groups are along the plane of the phenyl ring (Table 1). The carbonyl group is involved in hydrogen bonding, unlike the case of 2-nitroacetanilide (Kashino et al., 1986). The packing in (I) is stabilized by N—H···O and C—H···O hydrogen bonds (Fig. 2 and Table 2).

Experimental top

The title compound was prepared by the direct reaction of 3-nitroaniline and acetic anyhdride at room tempertaure for 10 min. Crystals of (I), suitable for single-crystal diffraction study, were grown at ambient temperature by slow evaporation of a methanol solution.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All e.s.d.'s are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles

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.
