title: 2-(Naphthalen-1-yl)-4-(naphthalen-1-yl-methyl-idene)-1,3-oxazol-5(4H)-one.
abstract: In the title compound, C(24)H(15)NO(2), the oxazole ring is oriented at dihedral angles of 10.09 (4) and 6.04 (4)° with respect to the mean planes of the naphthalene ring systems, while the two naphthalene ring systems make a dihedral angle of 4.32 (3)°. Intra-molecular C-H⋯N hydrogen bonds link the oxazole N atom to the naphthalene ring systems. In the crystal, inter-molecular weak C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. π-π contacts between the oxazole and naphthalene rings and between the naphthalene ring systems [centroid-centroid distances = 3.5947 (9) and 3.7981 (9) Å] may further stabilize the crystal structure. Three weak C-H⋯π inter-actions also occur.
