In the title molecule, C13H8N4O7, the amide fragment has an anti configuration. The mean planes of the two benzene rings form a dihedral angle of 7.78 (4)°. The mean planes of the three nitro groups are twisted by 6.82 (3), 5.01 (4) and 18.94 (7)° with respect to the benzene rings to which they are attached. In the crystal, molecules are linked by weak intermolecular N—H⋯O hydrogen bonds into chains along [100].

3,5-Dinitrobenzoyl chloride (1.15 g, 5 mmol) dissolved in tetrahydrofuran (10 ml) was added to 4-nitroaniline (0.69 g, 5 mmol) dissolved in tetrahydrofuran (5 ml), the reaction mixture was refluxed for 2 h, then cooled to ambient temperature and filtered to remove the tetrahydrofuran. The precipitate was dissolved in methanol/tetrahydrofuran/ethyl acetate (1:1:1) and the solution was allowed to stand for a few days at ambient temperature, after which time colorless plates of the title compound suitable for X-ray diffraction were obtaind.
H atoms were placed in idealized positions and allowed to ride on theirrespective parent atoms, with C—H = 0.93Å, N-H = 0.86Å and with Uiso(H) = 1.2Ueq(C,N).
N-substituted benzamides have numerous pharmaceutical and synthetic application (Saeed et al. 2010). In this paper, we report the structure of the title compound (I). The molecular structure of (I) is shown in Fig. 1. The bond lengths are within normal ranges (Allen et al. 1987). The amide N—H and C═O bonds in the molecule comprising the crystallographic are trans to each other and similar to those observed in 2-Hydroxy-N-(3-nitrophenyl)benzamide (Raza et al. 2010) and 2-chloro-N-(phenyl)-benzamide (NP2CBA) (Gowda et al., 2003). The mean planes of the two benzene rings form a dihedral angle of 7.78 (4)°. The mean planes of the three nitro groups are twisted by 6.82 (3)°, 5.01 (4)° and 18.94 (7)° with respect to the benzene rings to which they are attached. In the molecules are linked by weak intermolecular N-H···O hydrogen bonds in chains along [100] (see Fig. 2).

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. |

N-substituted benzamides have numerous pharmaceutical and synthetic application (Saeed et al. 2010). In this paper, we report the structure of the title compound (I). The molecular structure of (I) is shown in Fig. 1. The bond lengths are within normal ranges (Allen et al. 1987). The amide N—H and C═O bonds in the molecule comprising the crystallographic asymmetric unit are trans to each other and similar to those observed in 2-Hydroxy-N-(3-nitrophenyl)benzamide (Raza et al. 2010) and 2-chloro-N-(phenyl)-benzamide (NP2CBA) (Gowda et al., 2003). The mean planes of the two benzene rings form a dihedral angle of 7.78 (4)°. The mean planes of the three nitro groups are twisted by 6.82 (3)°, 5.01 (4)° and 18.94 (7)° with respect to the benzene rings to which they are attached. In the crystal structure, molecules are linked by weak intermolecular N-H···O hydrogen bonds in chains along [100] (see Fig. 2).
