In the title mol-ecule, C(19)H(17)N(3)O(6), the indole ring system is essentially planar (r.m.s. deviation = 0.009 Å) and forms a dihedral angle of 31.96 (9)° with the nitro-substituted benzene ring. In the crystal, mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming inversion dimers which are connected by further N-H⋯O hydrogen bonds into a two-dimensional network parallel to (102).
在标题分子C(19)H(17)N(3)O(6)中,吲哚环系基本呈平面状(均方根偏差 = 0.009 Å),并与硝基取代的苯环形成31.96 (9)°的二面角。在晶体中,分子通过N—H⋯O氢键对相连,形成反演二聚体,这些二聚体通过进一步的N—H⋯O氢键连接成平行于(102)的二维网络。
