Comment top

The Lewis base 4-(4-nitrobenzyl)pyridine (NBP) is an analogue of 2-(2,4-dinitrobenzyl)pyridine (DNBP) which is significant because of its unusual photochromic behaviour in the solid state, although NBP does not possess such properties. The structure of DNBP has been determined (Seff & Trueblood, 1968; Scherl et al., 1996; Naumov et al., 2002), as well that of its isomer 4-(2,4-dinitrobenzyl)pyridine (Ottersen & Seff (1974), but the structure of NBP itself is not known. A structure of a cocrystal adduct of NBP with 4-aminobenzoic acid has been reported (Smith et al., 1997).

Our reaction of NBP with 5-nitrosalicylic acid (5-NSA) gave the title compound C12H11N2O2+ C7H4NO5- (I), the structure of which is reported here. The acid 5-NSA has proved useful for formation of crystalline salts with a number of Lewis bases (Smith et al., 1996; Smith et al., 2005; Smith et al., 2006). With the title compound (I) (Fig. 1), the NBP cations and 5-NSA anions interact through asymmetric cyclic N+–H···O,O'carboxyl hydrogen-bonding associations (Table 1), giving discrete heterodimers [graph set R21(4) (Etter et al., 1990)]. There are weak cation–anion π–π aromatic ring interactions present in the crystal packing [minimum ring centroid separation between rings N1–C6 and C1A–C6A, 3.7166 (9) Å] (Fig. 2). With the NBP cation the two rings are approximately normal to each other [torsion angle C3–C4–C42–C11, -77.72 (17)°] with the nitro group close to coplanar with the benzene ring [torsion angle C31–C41–N41–O42, 170.27 (13)°]. The usual intramolecular phenolO—H···Ocarboxyl hydrogen bond [2.4623 (17) Å] is present in the 5-NSA anion which, including the nitro group is close to planar [torsion angles C2A–C1A–C11A–O11A, -173.72 (13)°; C4A–C5A–N5A–O52A, 177.68 (13)°].

Experimental top

The title compound was synthesized by heating together under reflux for 10 minutes, 1 mmol quantities of 4-(4-nitrobenzyl)pyridine with 5-nitrosalicylic 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 crystal aggregates (m.p. 416–417 K) from which a block section was cleaved for the X-ray analysis.

Refinement top

Hydrogen atoms involved in hydrogen-bonding interactions were located by difference methods and their positional and isotropic displacement parameters were refined. The other H-atoms were included in the refinement at calculated positions [C–H = 0.93 Å (aromatic) and 0.97 Å (aliphatic) and Uiso(H) = 1.2Ueq(C)], using a riding-model approximation.

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 esds 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.
