In the title compound, C27H21ClN2O4, the mean planes of the two indole ring systems (r.m.s. deviations = 0.021 and 0.024 Å) are approximately perpendicular to one another, with a dihedral angle of 79.54 (12)°. The benzene ring is twisted with respect to the mean planes of the two indole ring systems at angles of 80.14 (15) and 86.30 (15)°. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, forming inversion dimers with an R (2) 2(18) ring motif. The dimers are linked by a further N-H⋯O hydrogen bond, forming chains along [100]. There are intra- and inter-molecular C-H⋯π inter-actions present, the latter linking the chains to form a three-dimensional supra-molecular structure.
在标题化合物C₂₇H₂₁ClN₂O₄中，两个吲哚环系统的平均平面（均方根偏差分别为0.021和0.024 Å）彼此近似垂直，二面角为79.54 (12)°。苯环相对于两个吲哚环系统的平均平面扭转，扭转角分别为80.14 (15)°和86.30 (15)°。在晶体中，分子通过N—H⋯O氢键相连，形成具有R (2) 2(18)环 motif的反演二聚体。这些二聚体通过另一个N—H⋯O氢键相连，沿[100]方向形成链状结构。存在分子内和分子间的C—H⋯π相互作用，后者将链连接起来形成三维超分子结构。
