(E)-2-[(2-Hydr­oxy-5-nitro­phen­yl)iminiometh­yl]-4-nitro­phenolate

Abstract

The title mol­ecule, C₁₃H₉N₃O₆, consists of a 2-hydr­oxy-5-nitro­phenyl­iminio group and a 4-nitro­phenolate group bonded to a methyl­ene C atom with both of the planar six-membered rings nearly in the plane of the mol­ecule [dihedral angle = 1.3 (4)°]. Each of the nitro O atoms is twisted slightly out of the plane of the mol­ecule. The amine group forms an intra­molecular hydrogen bond with both nearby O atoms, each of which has partial occupancy of attached H atoms [0.36 (3) and 0.64 (3)]. An extended π-delocalization throughout the entire mol­ecule exists producing a zwitterionic effect in this region of the mol­ecule. The shortened phenolate C—O bond [1.2749 (19)°], in concert with the slightly longer phenol C—O bond [1.3316 (19) Å], provides evidence for this effect. The crystal packing is influenced by extensive strong inter­molecular O—H⋯O hydrogen bonding between the depicted phenolate and hydr­oxy O atoms and their respective H atoms within the π-delocalized region of the mol­ecule. As a result, mol­ecules are linked into an infinite polymeric chain diagonally along the [110] plane of the unit cell in an alternate inverted pattern. A MOPAC AM1 calculation provides support for these observations.

Comment

Schiff bases have a wide range of application in chemistry. The title compound, a Schiff base derivative, was synthesized under microwave conditions and recrystallized from ethanol to give brown crystals. The structural data shows that it exists as an iminio-phenolate zwitterion in the solid state. Typically, keto-amine tautomer behavior has been observed in related derivative compounds (Butcher et al. (2007); Jasinski et al. (2007); Gül et al. (2007); Odabaşoğlu et al. (2006)); Ersanlı et al. (2003)). Compounds of this type can be used as anion sensors in acetonitrile (Hijji et al. (2008)) that tend to exist in the keto-amine form, which is generally favored over the phenol-imine form in the solid state. Introduction of electron deficient groups to the aromatic rings tends to increase the acidity of the phenolic proton.

The title molecule, C₁₃H₉N₃O₆, consists of a 2-hydroxy-5-nitrophenyliminio group and a 4-nitrophenolate group bonded to a methylene carbon atom with both of the planar six-membered rings nearly in the plane of the molecule. The dihedral angle between the mean planes of the phenyl and phenolate rings measures 1.3 (4)°. Each of the nitro oxygen atoms are twisted slightly out of the plane of the molecule [torsion angles = 172.16 (17)° (O3—N2—C4—C5); -7.1 (2)° (O4—N2—C4—C5); -7.6 (3)° (O3—N2—C4—C3); 173.17 (15)° (O4—N2—C4—C3); and 178.63 (16)° (O6—N3—C12—C13); -3.4 (3)° (O5—N3—C12—C13); 174.28 (18)° (O5—N3—C12—C11); -3.7 (3)° (O6—N3—C12—C11)]. The phenolate (O1) and hydroxy (O2) oxygen atoms are essentially in the plane of the molecule [torsion angles = 179.03 (16)° (O1—C1—C6—C5); 0.5 (3)° (O1—C1—C6—C7); 179.31 (18)° (O2—C9—C10—C11); -177.90 (15)° (C13—C8—C9—O2)]. The imino group forms an intramolecular hydrogen bond with each of the nearby oxygen atoms (O1 and O2) which have partial occupancy of hydrogen atoms (H1O [0.36 (3)] and H2O [0.64 (3)], respectively) (see Fig. 1 which shows only the predominant component, H2O, and Table 2). There appears to be an extended π delocalization effect throughout the entire molecule producing a zwitterionic effect in this region of the molecule. The shortened C1—O1 bond (1.2749 (19) Å in concert with the slightly longer C9—O2 bond (1.3316 (19) Å) provide structural evidence for this effect.

Crystal packing is influenced by extensive strong intermolecular O—H···O hydrogen bonding between the depicted phenolate and hydroxy oxygen atoms (O1 & O2) and their respective hydrogen atoms within the π delocalized region (O1—H1O(0.36)···O2; 2.5570 (16) Å) and O2—H2O(0.64)···O1; 2.5570 (16) Å) of the molecule. Additional weak intermolecular C—H···O hydrogen bond interactions occur involving the methylene carbon (C7) and the phenyl (C10 & C13) and phenolate (C3) groups (Fig. 2), respectively. All of the hydrogen bond interactions are summarized in Table 1. As a result the molecules are linked into an infinite polymeric chain diagonally along the [110] plane of the unit cell in an alternate inverted pattern (Fig. 2). In addition, weak Cg1–Cg1 (3.517 (2) Å; slippage = 1.09 (8)°; -x, 1 - y, -z) and Cg1–Cg2 (3.830 (6) Å; x, y - 1, z) π-π stacking ring interactions also occur where Cg1 = center of gravity of the C1–C6 ring and Cg2 = center of gravity of the C8–C13 ring.

After a MOPAC AMI calculation [Austin Model 1 approximation together with the Hartree-Fock closed-shell (restricted) wavefunction was used and minimizations were terminated at an r.m.s. gradient of less than 0.01 kJ mol^-1 Å^-1] of the zwitterionic form with WebMO Pro (Schmidt, 2007). As a result of this energy minimization, the dihedral angle between the phenyl and phenolate rings changes from 1.3 (4)° in the crystal structure to 7.6 (6)°, producing a slightly more twisted molecule than the nearly planar molecule in the crystalline environment. Thus, it is apparent that the extensive hydrogen bonding and π-π stacking intermolecular interactions significantly influence crystal packing with this molecule.

Experimental

The title compound was synthesized as follows: 2-amino-4-nitrophenol (0.15 g, 1 mmol) and 2-hydroxy-5-nitrobenzaldehyde (0.17 g, 1 mmol) were mixed in a loosely capped vial. The reaction mixture was allowed to heat at full power in a conventional microwave for 8 minutes. The compound was recrystallized from ethanol affording a brown solid (0.20 g, 68%). (mp 591–593 K) ¹H-NMR (400 MHz, DMSO-d₆), δ (p.p.m.): 14.64 (s, br, 1H), 11.74 (s, br, 1H) 9.37 (s, 1H), 8.72 (d, J = 2.87 Hz, 1 H), 8.41 (d, J = 3.3 Hz, 1H), 8..27 (dd, J = 9.2, 3.1 Hz, 1H), 8.13 (1H, dd, J = 9.06, 2.7 Hz, 1 H), 7.16 (d, J = 9.1 Hz, 1H), 7.09 (d, J = 9.2 Hz, 1H), ¹³C-NMR (100 MHz, DMSO-d₆) δ (p.p.m.): 167.90, 162.13, 157.48, 139.89, 138.76, 133.40, 128.95, 128.69, 124.51, 118.78, 118.25, 116.54, 115.24.

Refinement

H1A, H1O and H2O were obtained from a difference Fourier map. The occupancies of H1O and H2O refined to values of 0.36 (3) and 0.64 (3), respectively. The rest of the H atoms were placed in their calculated positions and then refined using the riding model with C(N,O)—H = 0.82 to 0.93 Å, and with U_iso(H) = 1.15–1.20U_eq(C,N).

Special details

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.
