(Received 29 April 2010; accepted 8 May 2010; online 9 June 2010)

There are two mol­ecules in the asymmetric unit of the title compound, C19H15NO2, in which the dihedral angles between the naphthalene ring system and the pyridine ring are 40.5 (3) and 41.2 (4)°. In the crystal, C—H⋯O hydrogen bonds link the mol­ecules.

Experimental top

In the presence of sodium hydroxide, 6-methoxy-2-naphthaldehyde and 1-(pyridin-2-yl)ethanone in liquid ammonia were stirred at 313 K for 4 h. Sodium hydroxide was filtered off and the filtrate was duluted with dichlormethane and washed by brine. The organic phase was dried over anhydrous sodium sulfate, filtered, and concentrated to give crude product which was recrystallised from from dichlormethane to give yellow blocks of (I).

Refinement top

The absolute structure of the title compound is indeterminate in the present refinement. H atoms were positioned geometrically, with C-H = 0.93, 0.97 and 0.96 Å for aromatic, methylene and methyl H, respectively, and constrained to ride on their parent atoms, with Uiso(H) = xUeq(C), where x = 1.5 for methyl H and x = 1.2 for all other H atoms.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
