In the title compound, C(33)H(28)N(2)O(4), the central pyrrolidine ring adopts a half-chair conformation. Both the indolinone and indanone groups are twisted, with their five-membered rings adopting a half-chair and an envelope conformation, respectively. The two benzene rings and the mean plane of the indolinone and indanone groups make dihedral angles of 71.98 (10), 84.32 (10), 86.26 (9) and 78.50 (9)°, respectively, with the central pyrrolidine ring. Intra-molecular C-H⋯O hydrogen bonds stabilize the mol-ecular conformation. In the crystal, pairs of inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers. The dimers are inter-connected into ribbons propagating along [110] via weak inter-molecular C-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯π and π-π [centroid-centroid distance = 3.6509 (11) Å] inter-actions are also observed.
在标题化合物C(33)H(28)N(2)O(4)中，中心吡咯烷环呈半椅式构象。吲哚啉酮和茚满二酮基团均呈扭曲状，其五元环分别呈半椅式和信封式构象。两个苯环与吲哚啉酮和茚满二酮基团的平均平面与中心吡咯烷环的二面角分别为71.98 (10)、84.32 (10)、86.26 (9)和78.50 (9)°。分子内C—H⋯O氢键稳定了分子构象。在晶体中，分子间N—H⋯O氢键对将分子连接成中心对称的二聚体。这些二聚体通过弱分子间C—H⋯O氢键相互连接成沿[110]方向延伸的带状结构。还观察到弱分子间C—H⋯π和π–π [质心-质心距离 = 3.6509 (11) Å]相互作用。
