In the structure of the title salt, C12H10N3O4+·C7H3N2O7−, the cations and the anions are linked by a single N+—H⋯Ocarbox­yl hydrogen bond, the discrete cation–anion unit having no inter­molecular associations other than weak cation–anion aromatic ring π–π inter­actions [ring centroid separation = 3.7320 (14) Å] and a number of weak inter-unit aromatic C—H⋯O contacts. An intramolecular C—H⋯O hydrox­yl–carboxyl hydrogen bond occurs in the anion.

Comment top

The Lewis base 2-(2,4-dinitrobenzyl)pyridine (DNBP) is unusual because of its photochromic properties, undergoing a reversible solid-state colour change from colourless to deep blue on irradiation with light of wavelength 400 nm or less. This is due to two-photon excitation giving nitro-assisted proton transfer (NAPT) involving an oxygen of the o-nitro substituent group and the pyridine N atom (Naumov et al., 2002). The structures of both the colourless form (Seff & Trueblood, 1968; Scherl et al., 1996) and the blue form (Naumov et al., 2002), have been determined as well, as that of the chloride (Naumov et al., 2005).

Our reaction of DNBP with a number of aromatic carboxylic and sulfonic acids in aqueous ethanol has previously provided only one crystalline compound: bis[2-(2,4-dinitrobenzyl)pyridinium] biphenyl-4,4'-disulfonate trihydrate, for which the structure was reported (Smith, Wermuth & Young, 2010). A second crystalline compound was subsequently obtained from the reaction of DNBP with 3,5-dinitrosalicylic acid (DNSA), the title compound anhydrous C12H10N3O4+.C7H3N2O7- (I), the structure of which is reported here. DNSA has been very useful as an acid capable of producing crystalline salts with a range of both aliphatic and aromatic Lewis bases and the structures of a large number of these are reported in the crystallographic literature, e.g. Smith et al. (2002, 2003, 2007) and Smith, Cotton et al. (2010).

With compound (I) (Fig. 1), a single cation–anion N+–H···Ocarboxyl hydrogen bond together with a weak aliphatic C–H···Ocarboxyl association (C71–H···O11A) (Table 1), form discrete cation–anion units. These units have no intermolecular interactions other than mostly weak aromatic C–H···O contacts [one is strong: C6–H···O31Aiii: symmetry code (iii), -x + 1, -y + 1, -z + 1], and also weak cation–anion π–π aromatic ring associations [ring centroid separation for C11–C61 to C1A–C6A, 3.7320 (14) Å] down the a axial direction (Fig. 2).

With the DNBP cation both nitro groups are rotated out of the plane of the benzene ring [torsion angles C11–C21–N21–O22, -151.4 (2)° and C31–C41–N41–O42, 149.9 (2)°]. In the DNSA anion, within the intramolecular hydroxyl–carboxyl hydrogen bond, the H atom is located on the hydroxyl group rather than being anti-related on the carboxyl group. (I) is only one of the ca 30% of the known examples of DNSA salts having this (Smith et al., 2007). The carboxyl group, as expected, is close to planar with the benzene ring [torsion angle C2A–C1A–C11A–O11A, 175.0 (2)°], while one nitro group is close to coplanar [torsion angle C4A–C5A–C51A–O52A, 177.6 (2)°], the other being rotated out of the plane [torsion angle C2A–C3A–C31A–O32A, -159.1 (2)°]. In the structure there is a short nonbonded contact across an inversion centre [O42···O42iv, 2.897 (3) Å: symmetry code (iv) -x + 1, -y, -z + 1], this O atom being associated with the large electron density maximum (0.75 e Å-3).

Experimental top

The title compound was synthesized by heating together under reflux for 10 minutes, 1 mmol quantities of 2-(2,4-dinitrobenzyl)pyridine and 3,5-dinitrosalicylic acid in 50 ml of 50% ethanol–water. After concentration to ca 30 ml, partial room temperature evaporation of the hot-filtered solution gave yellow plates (m.p. 383 K) having 90° yellow–colourless orientational dichroism in the crystals.

Refinement top

The two hydrogen atoms involved in hydrogen-bonding interactions were located by difference methods and were constrained in the refinement with the other H atoms at calculated positions [C–H = 0.93 Å (aromatic) and 0.97 Å (aliphatic)] and with Uiso(H) = 1.2Ueq(C), using a riding-model approximation. There is a larger than normal maximum residual electron density peak (0.75 e Å-3) which is located ca 1.56 Å from the nitro O atom O42).

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.
