The title 2:1 co-crystal, 2C12H10N2·C8H6O4, crystallizes with one mol­ecule of 4-[(E)-2-(pyridin-2-yl)ethen­yl]pyridine (A) and one half-mol­ecule of terephthalic acid (B) in the asymmetric unit. In the crystal, the components are linked through heterodimeric COOH⋯Npyridine synthons, forming linear aggregates of composition –ABAB–. Further linkage through weak C—H⋯O and C—H⋯π inter­actions gives two-dimensional hydrogen-bonded undulating sheets propagating in the [100] and [010] directions. These layers are connected through additional weak C—H⋯O contacts, forming a three-dimensional structure.

Comment top

Supramolecular crystal engineering has attracted growing interest over the past few decades because of its importance in biological systems, molecular recognition (Simon et al., 2000), pharmaceutical chemistry (Weyna et al., 2009) and materials chemistry (Yan et al., 2012). Aromatic carboxylic acids form reliable supramolecular synthons for the construction of novel organic networks by hydrogen bonding and ππ interactions (Desiraju, 1995), and numerous studies have focused on hydrogen bonding between carboxylic acids and pyridine molecules (Bhogala & Nangia, 2003; Santra et al., 2008; Moon & Park, 2012; Ebenezer & Muthiah, 2012). Herein, we report on the solid-state structure of a 2:1 co-crystal formed between an asymmetric bipyridine [4-((E)-2-(pyridin-2-yl)ethenyl)pyridine] and a symmetric dicarboxylic acid [terephthalic acid].

The molecular structure of the title compound is shown in Fig. 1. The asymmetric unit contains one molecule of 4-((E)-2-(pyridin-2-yl)ethenyl)pyridine and half a molecule of terephthalic acid located on a crystallographic inversion center. Both components have almost planar molecular structures as seen from the C10—C11—C12—N2 torsion angle of -4.2 (3)° for the bipyridine molecule and the O1—C4—C1—C2 torsion angle of -6.0 (3)° for the terephthalic acid.

In the crystal lattice, each terephthalic acid is linked to two bipyridine molecules through intermolecular O—H···N and C—H···O interactions giving the well known heterodimeric COOH···Npyridine synthon. The so formed linear aggregates are connected through additional weak C—H···O contacts to generate tapes parallel to the (1–41) series of planes, which through C—H···π contacts generate undulating two-dimensional supramolecular layers (Fig. 2 and Table 1). In the third dimension, these layers are interconnected through additional weak C—H···O contacts. Interestingly, the 2-pyridine nitrogen atom is not involved in short intermolecular hydrogen bonding interactions.

Experimental top

0.200 g (1.10 mmol) of 4-((E)-2-(pyridin-2-yl)ethenyl)pyridine and 0.180 g (1.10 mmol) of terephthalic acid were ground in a mortar for 20 min after adding 3 drops of CH3OH. The resulting powder was then dissolved in 10 ml of CH3OH and kept for crystallization by slow evaporation of the solvent at ambient conditions to give colourless block-like crystals, suitable for single-crystal X-ray diffraction analysis, after one week. Spectroscopic and TGA data for the title compound are available in the archived CIF.

Refinement top

H atoms bonded to C atoms were positioned geometrically and constrained using the riding-model approximation [aryl C—H = 0.93 A and Uiso(H) = 1.2Ueq(C)]. The H atom bonded to O was initially located in a difference Fourier map, then the position was refined with the O—H distance restraint of 0.84 (1) Å with Uiso(H) = 1.5Ueq(O). One reflection that was located behind the beam stop has been omitted during the refinement (020).

Experimental. Spectroscopic and TGA data for the title compound:

IR (KBr): 3056, 2944, 1706, 1683, 1606, 1581, 1504, 1425, 1290 y 731 cm-1. 1H-RMN (200 MHz, DMSO-d6, TMS): δ 8.59 (m, 3H), 8.04 (s, 4H), 7.83 (td, J = 0.8, 4 Hz, 1H), 7.61 (m, 5H), 7.32 (m, 1H). TGA Calcd. for 2 C12H10N2: 68.69. Found: 69.27% (303 - 533 K).

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.
