In the title compound, C30H20N2, the anthracene ring system is approximately planar [maximum deviation = 0.035 (2) Å] and is nearly perpendicular to the central pyridine ring, making a dihedral angle of 75.73 (7)°. The terminal pyridine ring and the phenyl ring are oriented at dihedral angles of 8.11 (10) and 13.22 (10)°, respectively, to the central pyridine ring.

3-(Anthracen-9-yl)-1-phenylprop-2-en-1-one (1.54 g, 5.0 mmol), 2-acetylpyridine (1.82 g, 15 mmol) and NaOH (0.20 g, 5.0 mmol) were crashed together with a pestle and mortar for 3 h. The light yellow powder was added to a stirred solution of ammonium acetate (15.4 g, 200.0 mmol) in ethanol (200 ml). The reaction mixture was heated at reflux. Thin layer
analysis tracking reaction, evaporated solvent, extracted with dichloromethane, and dried to afford the product. It was purified by flash on silica. Elution with petroleum/ethyl acetate (10:1) gave a white solid (yield; 1.3 g, 65%). Single crystals of (I) were grown by slow evaporation of a dichloromethane/ethyl acetate (1:1) solution.H atoms were positioned geometrically with C—H = 0.93 Å and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(C).
The aromatic conjugated organic compounds are investigated with great interest due to their potential applications in optical image processing, all-optical switching, organic light emitting diodes (OLEDs) and integrated optical devices (Nishihara et al., 1989; Mi et al., 2003; Roberto et al., 2000). As a part of our continuing studies of the synthesis and characterization of optical materials, we have prepared a new anthracene derivative containing two pyridine rings and investigated its crystal structure.
The molecule structure of (I) is shown in Fig. 1. Two pyridine rings makes the dihedral angle of 8.11 (10)°. The anthracen moiety is almost planar, and make the dihedral angles of 75.73 (7)° and 67.84 (2)° with two pyridine rings, respectively.

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. |

The aromatic conjugated organic compounds are investigated with great interest due to their potential applications in optical image processing, all-optical switching, organic light emitting diodes (OLEDs) and integrated optical devices (Nishihara et al., 1989; Mi et al., 2003; Roberto et al., 2000). As a part of our continuing studies of the synthesis and characterization of optical materials, we have prepared a new anthracene derivative containing two pyridine rings and investigated its crystal structure.
The molecule structure of (I) is shown in Fig. 1. Two pyridine rings makes the dihedral angle of 8.11 (10)°. The anthracen moiety is almost planar, and make the dihedral angles of 75.73 (7)° and 67.84 (2)° with two pyridine rings, respectively.
