In the title compound, C15H11N, the mean planes of the aromatic moieties are inclined to one another by 72.9 (1)°. The crystal is stabilized by π–π stacking inter­actions between the pyridine rings of inversion-related mol­ecules, with a centroid–centroid distance of 3.772 (2) Å. In addition, C—H⋯π contacts involving an α-C—H group of the pyridine ring and the nonsubstituted ring of the naphthalene unit are observed, giving rise to a herringbone-type supramolecular architecture of the naphthalene moiety being contained in the molecule.

Comment top

Molecules having a defined structure with rather predictable supramolecular interactions of their construction elements and functional groups such as π···π (James, 2004) or weak hydrogen bonding contacts (Desiraju & Steiner,1999) are helpful in gaining deeper insight into the principles of crystal engineering (Tiekink et al., 2010). This has stimulated to determine the crystal structure of the title compound being composed of two π-systems of different electronic nature (naphthalene and pyridine units) and having potential capability of weak C—H···π (Nishio et al., 2009) or C—H···N bonding (Desiraju & Steiner, 1999). In the crystal structure, the bond distances both of the naphthalene (AB) and pyridine (C) parts agree well with those found for related compounds (Boeyens et al., (1988) Suthar et al., 2005). The naphthalene moiety shows a slight distortion from strict planarity with largest atomic distances from the best plane being 0.029 (1) Å for C7 and -0.030 (2) Å for C9. The mean planes of the naphthalene and pyridine moieties are inclined to one another by 72.9 (1) ° (Fig. 1). Contrary to expectations, the nitrogen of the heterocyclic ring is excluded from molecular association. Instead, the crystal structure is stabilized by weaker C—H···π contacts with the non-substituted ring of the naphthalene unit (B) acting as an acceptor [C6—H6···centroid(B) 2.69 Å, 161 °, C14—H14···centroid(B) 2.84 Å, 146 °]. Moreover, the centre···centre distance of 3.772 (2) Å between the pyridine rings of inversion related molecules indicate the occurrence of π···π stacking interactions (Fig. 2). In a similar fashion as in the crystal structure of naphthalene (Fabbiani et al., 2006), each molecule is surrounded by another six molecules so that their naphthalene elements form a herringbone motif.

Experimental top

Preparation of the title compound was achieved by a Suzuki cross coupling reaction (Miyaura et al., 1981) between 2-(1-naphthyl)-1,3,2-dioxaborolane (Broutin & Colobert, 2005) (4.94 g, 25 mmol) and 4-bromopyridinium hydrochloride (4.87 g, 25 mmol) in the presence of tetrakis(triphenylphosphane)palladium (0.52 g, 0.45 mmol) and potassium phosphate (7.24 g, 34 mmol) in 136 ml degassed N,N-dimethylformamide. The resulting mixture was heated to 100 °C and stirred at this temperature for 6 h. After cooling to room temperature, the mixture was extracted with toluene. The extract was washed with saturated aqueous NaCl solution and dried (Na2SO4). Evaporation of the solvent and crystallization from ethanol yielded 1.10 g (24%) colourless crystals. M.p. (366–368 K). Spectroscopic data correspond to those reported for the compound obtained via a different synthetic route (Molander & Beaumard, 2010).

Aromatic H atoms were positioned geometrically and allowed to ride on their respective parent atoms, with C—H = 0.95 Å and Uiso(H) = 1.2 Ueq(C).

Special details top

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.
