(Received 6 August 2010; accepted 9 August 2010; online 28 August 2010)

In the crystal structure of title compound, C13H10N2O4, as expected, the nitro- and hy­droxy-substituted benzene rings are planar with r. m. s. deviations of 0.0037 and 0.0014 Å, respectively, but are twisted slightly relative to each other, making a dihedral angle of 12.23 (7)°. The nitro group is only slightly twisted [by 2.71 (16)°] with respect to its parent ring. An intra­molecular N—H⋯O hydrogen bond forms an S(6) ring motif. Inter­molecular N—H⋯O and O—H⋯O hydrogen bonds build up sheets parallel to the ab plane. Futhermore, weak π–π inter­actions [centroid–centroid distances = 3.7150 (8) 3.7342 (6) and 3.9421 (8) Å] between the rings yield a three-dimensional network.

Comment top

Asymmetric synthesis is gaining much importance. Aim of our work is the formation of various chiral benzoxazepines and their derivatives that have been reported as anti-tumor (Samanta et al., 2010) and anti-HIV agents (Fattorusso et al., 2005). The title compound (I, Fig.1) has been synthesized as a precursor for variously substituted chiral benzoxazepines.

We have reported the crystal structures of (II) i.e., 2-hydroxy-3-nitro-N-phenylbenzamide (Raza et al., 2009) and (III) 2-hydroxy-5-nitro-N-phenylbenzamide (Raza et al., 2010). The title compound differs from (II) and (III) due to the attachement of nitro group at different position.

In (I), the nitro and hydroxy substituted phenyl rings A (C1–C6) and B (C8—C13) are planar with r. m. s. deviation of 0.0037 and 0.0014 Å, respectively. The central group C (N1/C7/O3) is of course planar. The dihedral angle between A/B, A/C and B/C is 12.23 (7)°, 6.13 (20)° and 18.35 (18)°, respectively. The nitro group is slightly twisted with respect to its parent phenyl ring making a dihedral angle of 2.71 (16)°. Bond distances and angles agree with related compounds (Raza et al., 2009,2010; Glidewell et al., 2006).

There exist intramolecular N—H···O hydrogen bond forming S(6) ring motifs (Bernstein et al., 1995). The molecules are stabilized in the form of two dimensional polymeric sheets due to intermolecular H-bondings of N—H···O and O—H···O types. The polymeric sheets extend in the ab-plane (Table 1, Fig. 2). Futhermore weak slippest π–π interactions between the phenyl rings yield a three dimensionnal network (Table 2).

Experimental top

3-Nitroaniline (4.14 g, 0.03 mol) was added to 2-hydroxybenzoyl chloride prepared by treating salicylic acid (4.14 g, 0.03 mol) with oxalyl chloride (2.80 ml, 4.00 g, 0.032 mol) using DMF in catalytic amount. The reaction mixture was refluxed for 2 h, cooled to room temperature, neutralized with aqueous NaHCO3 (10%) and extracted with EtOAc (3×25 ml). The organic extract was combined, dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. The title compound (I) was mechanically separated as yellow cubical crystals.

Refinement top

Although H atoms were appeared in difference Fourier map but were positioned geometrically with (O–H = 0.82, N–H= 0.86 and C–H = 0.93 Å) and refined as riding with Uiso(H) = xUeq(C, N, O), where x = 1.5 for hydroxy and x = 1.2 for other H atoms.

Special details top

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su'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.
