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.
在标题化合物C₂₄H₁₅NO₂中，恶唑环相对于萘环系统的平均平面的二面角为10.09（4）°和6.04（4）°，而两个萘环系统之间的二面角为4.32（3）°。分子内C—H⋯N氢键将恶唑N原子与萘环系统相连。在晶体中，分子间弱C—H⋯O氢键将分子连接成中心对称的二聚体。恶唑环与萘环之间以及萘环系统之间的π-π接触[质心-质心距离 = 3.5947（9）和3.7981（9）Å]可能进一步稳定晶体结构。还存在三种弱C—H⋯π相互作用。
