10 ml 2-methylpyridine was added to a 20-ml hot aqueous solution of benzylic acid (1.0 mmol, 0.23 g) and the mixture was stirred for 10 minutes under the temperature of 373 K. Then, the solution was filtered, and the filtrate was kept at room temperature. After 5 d, colorless crystals of (I) were obtained.
The N– and O-bound H atoms were located in a difference map and refined with distance restraints N—H = 0.86 (1) Å and O—H = 0.82 (1) Å; their Uiso values were freely refined.
The C-bound H atoms were placed in calculated positions (C—H = 0.93–0.96 Å) and refined as riding, with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C).
Supramolecular hydrogen-bonded molecular networks are of great current interest (Zhang & Chen, 2005). In this paper, we report the title supramolecular salt, (I), in which the component ions are connected by hydrogen bonds.
Compound (I) contains two pairs of 2-methylpyridinium anions and benzylate anions, in which each 2-methylpyridinium anion interacts with its adjacent benzylate anion through an intermolecular N—H···O hydrogen bond (Fig. 1 and Table 1). In addition, an intramolecular O—H···O hydrogen bond also exists in each benzylate anion and forms an S(6) ring. These O—H···O bonds are bifurcated to nearby O atoms, thus forming inversion dimers.

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. |

Supramolecular hydrogen-bonded molecular networks are of great current interest (Zhang & Chen, 2005). In this paper, we report the title supramolecular salt, (I), in which the component ions are connected by hydrogen bonds.
Compound (I) contains two pairs of 2-methylpyridinium anions and benzylate anions, in which each 2-methylpyridinium anion interacts with its adjacent benzylate anion through an intermolecular N—H···O hydrogen bond (Fig. 1 and Table 1). In addition, an intramolecular O—H···O hydrogen bond also exists in each benzylate anion and forms an S(6) ring. These O—H···O bonds are bifurcated to nearby O atoms, thus forming inversion dimers.
