The title compound, C(29)H(29)NO(3), the nearly planar nine-membered indanedione ring [maximum deviation = 0.027 (2) Å] is located approximately parallel to its carrier pyridine ring [maximum deviation = 0.021 (2) Å] with a dihedral angle of 1.8 (1)° between the planes. However, because of steric hindrance, the benzene ring [maximum deviation = 0.006 (2) Å] is not parallel to the pyridine ring [dihedral angle = 37.29 (8)°]. The mol-ecules display numerous inter-molecular π-π inter-actions between the five- and six-membered rings, the shortest centroid-centroid distance being 3.796 (2) Å. There are inter- and intra-molecular O-H⋯O and C-H⋯O hydrogen bonds.
标题化合物C(29)H(29)NO(3)中，近乎平面的九元茚二酮环[最大偏差 = 0.027 (2) Å]与其载体吡啶环[最大偏差 = 0.021 (2) Å]近似平行，平面间二面角为1.8 (1)°。然而，由于空间位阻，苯环[最大偏差 = 0.006 (2) Å]与吡啶环不平行[二面角 = 37.29 (8)°]。分子在五元环和六元环之间展现出众多分子间π-π相互作用，最短质心间距为3.796 (2) Å。存在分子间和分子内的O-H⋯O和C-H⋯O氢键。
