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 inter-actions between the pyridine rings of inversion-related mol-ecules, 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 naphtha...

The mol-ecule of the title compound, C(34)H(24)O(4), possesses crystallographically imposed twofold C(2) symmetry. The two 2-naphthoyl groups at the 1- and 8-positions of the central naphthalene ring are aligned almost anti-parallel [5.21 (5)°]. The dihedral angle between the central 2,7-dimeth-oxy-naphthalene unit and the terminal naphthyl groups is 75.13 (4)°. In the crystal, weak C-H⋯O hydro...
