In the title compound, C(24)H(24)N(2)O(2), the five-membered ring of the indoline ring system adopts an envelope conformation with the spiro C atom at the flap. The dihedral angle between the benzene ring of the indoline ring system and the naphthalene ring system is 71.70 (7)°. In the crystal structure, pair of weak C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
在标题化合物C₂₄H₂₄N₂O₂中,吲哚啉环系的五元环呈信封式构象,螺碳原子位于折边上。吲哚啉环系的苯环与萘环系之间的二面角为71.70 (7)°。在晶体结构中,一对弱的C—H⋯O氢键将分子连接成中心对称的二聚体。
