(Received 13 May 2009; accepted 19 June 2009; online 24 June 2009)

The title adduct, C7H5NO4·C6H6N2O3, forms part of an ongoing study of the design of non-centrosymmetric systems based on 3-methy-4-nitro­pyridine 1-oxide. The components of the adduct are linked by inter­molecular O—H⋯O hydrogen bonds. The rings of the two components are nearly planar, with a dihedral angle of 11.9 (2)° between the planes. The supra­molecular structure shows that mol­ecules of the title complex are linked into sheets by a combination of strong O—H⋯O and weak C—H⋯O hydrogen bonds.

Comment top

Within the family of crystal compounds having the N-oxide group, the 3-methyl-4-nitropyridine 1-oxide (POM) is one of the best electro-optic materials in the visible range (Sapriel et al., 1989). The title work is part of a series of structural studies on molecular complexes, formed by hydrogen bonds, with potential non-linear optical applications (Moreno-Fuquen et al., 2002). To complement the crystallographic information available on compounds based on POM complexes, to study its supramolecular behaviour, and to analyze the type of hydrogen-bonds formed in the adduct, a determination of the 3-nitrobenzoic acid (NBA) and POM, adduct (I), was undertaken. The free molecular systems POM and NBA have been reported in the literature (Baert et al., 1988; Dhaneshwar et al., 1975), respectivelly, and they can be used as reference systems to compare with the structural characteristics of (I). The title complex (I) is held together by a strong intermolecular hydrogen bond (Emsley, 1984) between the N—O group of the POM molecule and the O—H group of the NBA molecule (Table 1.). A displacement ellipsoid plot of (I), with the atomic numbering scheme is shown in Figure 1. The title compound shows an O3···O5 bond length of 2.578 (3) Å and O3—H31···O5 bond angle of 170 (5)°. The dihedral angle between the planes of the POM and MABA rings of (I) is 11.9 (2)°. The presence of an additional C10—H10···O4 intermolecular hydrogen bond allows the formation of R22(8) rings between the molecules in the adduct (I). The free NBA and other organic acids usually exist as dimeric pairs forming R22(8) rings between the molecules. In a first stage, for the formation of the adduct (I), the NBA molecule breaks the hydrogen bond compromised in the formation of the dimer and subsequently the NBA molecule fits the C—O bonds in order to form the new R22(8) ring with the POM molecule. Indeed, from symmetric C—O bonds (C···O = 1.256 (4) Å) in the free NBA molecule (Dhaneshwar et al., 1975), the C—O bond lengths change to 1.205 (3) Å and 1.311 (4) Å in the adduct (I). Additionally, the C(5)—C(7) bond length in the NBA free molecule changes from 1.488 (3) Å to 1.502 (4) Å, as a result of the formation of the title complex. The molecules which form the title adduct (I), are linked into sheets by a combination of O—H···O and C—H···O hydrogen bonds (Table 1) and these interactions define the bulk structure of the crystal. In a first substructure, the formation of a centrosymmetric rings generated by pairs of O—H···O and C—H···O hydrogen bonds is observed (Fig. 2). The carboxyl O3 atom of NBA molecule acts as hydrogen bond donor to N-oxide atom O5 of POM, in the molecule at (x, y, z) and C10 atom of POM in the molecule at (x, y, z) acts as hydrogen bond donor to carboxyl atom O4 in the molecule at (x,y,z) so forming by inversion a centrosymmetric R22(8) ring (Etter, 1990). In addition, atoms O3 and O5 in the molecule at (x,y,z) act as hydrogen bond acceptors from the atoms C11 and C13 in the molecule at (-1 - x, 2 - y, 1 - z) respectively, so forming by inversion R23(8) and R22(8) edge-fused centrosymmetric rings. Prolonging the growth of the crystal in the [-110] direction, the nitro O7 atom in the molecule at (x, y, z) acts as hydrogen bond acceptor from the atom C13 in the molecule at (-x + 1/2, y - 1/2,-z + 1/2), so forming R22(12) centrosymmetric ring. In a second substructure, atom C2 in the molecule at (x, y, z) acts as hydrogen bond donor to nitro O1 atom in the molecule at (-x + 3/2, 1/2 + y, 1/2 - z). In addition, atom O2 in the molecule at (x, y, z) acts as hydrogen bond donor to C9 atom in the molecule at (-x + 1/2, y - 1/2, -z + 1/2). The propagation of this interaction forms a C(5) (Etter, 1990) chain running along [010] direction (Fig. 3). The combination of these substructures is sufficient to generate a continuous framework structure. The presence of a centre of symmetry in the crystal inhibits the non-linear optical response.

Experimental top

The synthesis of the title compound (I) was carried out by slow evaporation of equimolar quantities of 3-nitrobenzoic acid (0.805 g, 0.0048 mol) and 3-methyl-4-nitropyridine 1-oxide (0.739 g) in 150 ml of dry acetonitrile. Pale-yellow prisms of good quality, suitable for x-ray analysis with a melting point of 589 (1) K were obtained. The initial reagents were purchased from Aldrich Chemical Co., and were used without additional purification.

Refinement top

All H-atoms were located from difference Fourier maps and then they were treated as riding atoms [Caro—H= 0.93 A°, and Csp3—H= 0.96 A°, Uiso(H)=1.2Ueq(Caro), Uiso(H)= 1.5Ueq(Csp3)).

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.
