The title compound, C13H11N3O3, is essentially planar (r.m.s. for the 19 non-H atoms = 0.031 Å), a conformation stabilized in part by intramolecular O—H⋯N and N—H⋯O hydrogen bonds. The configuration about the imine bond [1.2919 (12) Å] is E. The presence of N—H⋯O(nitro) hydrogen bonds leads to the formation of supramolecular tapes in the These are connected into layers by π–π interactions [centroid–centroid distance = 3.6046 (6) Å] occurring between the hydroxy- and amino-substituted benzene rings.

A solution of 4-nitrobenzene-1,3-diamine (10 mmol) in methanol (50 ml) was added drop wise to a solution of salicylaldehyde (10 mmol) in methanol (50 ml). The mixture was stirred for 5 h. The resulting solution was filtered to obtain a Schiff base, and dried. Single crystals of the title compound were obtained by using the branched tube method (Harrowfield et al., 1996). Thus, the Schiff base (5 mmol) was placed in the arm to be heated. Methanol was added to fill both arms, and then the arm to be heated was placed in a bath at 333 K. After 2 days, orange crystals were deposited in the cooler arm, which were filtered, washed with water and air dried. Yield: 88%. M.pt.: 432 K.
Carbon-bound H-atoms were placed in calculated positions [C—H 0.95 Å, Uiso(H) = 1.2Ueq(C)] and were included in the
in the riding model approximation. The O—H and N—H H atoms were located from a difference map and refined with O—H = 0.84±0.01 Å and N—H = 0.88±0.01 Å, respectively, and with unconstrained Uiso(H) values.Data collection: CrysAlis PRO (Agilent, 2010); cell

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. |

In continuation of structural studies of Schiff bases (Prasath et al., 2010; Shahverdizadeh & Tiekink, 2011), the title compound was synthesized and characterized crystallographically.
The molecule of (I), Fig. 1, is planar with the r.m.s. deviation of the 19 non-hydrogen atoms being 0.031 Å; the maximum and minimum deviations are 0.066 (1) Å for atom C12 and -0.062 (1) Å for atom O2. The observed planar conformation is stabilized in part by intramolecular O—H···N and N—H···O hydrogen bonds, Table 1. The amino group is planar with the sum of the angles about the N2 atom being approximately 359°. The configuration about the N1═ C7 bond [1.2919 (12) Å] is E, and the hydroxy and amino groups are syn.
In the crystal structure, supramolecular tapes in the (1 1 1) plane are formed via N—H···O(nitro) hydrogen bonds, Fig. 2 and Table 1. The spine of the tape comprises alternating 12-membered rectangular {···HNC2NO}2 and square {···HNH···ONO}2 synthons. The tapes are connected into layers via π–π interactions occurring between the hydroxy- and amino-benzene rings [centroid(C1–C6)···centroid(C8–C13)i distance = 3.6046 (6) Å for i: 1 - x, -y, 1 - z].
