Crystal structure of dimethyl 3,3′-[(3-nitrophenyl)methylene]bis(1H-indole-2-carboxylate) ethanol monosolvate

In the title compound, C₂₇H₂₁N₃O₆·C₂H₅OH, the indole ring systems are approximately perpendicular to each other, with a dihedral angle of 89.3 (5)°; the plane of the benzene ring is oriented with respect to the indole ring systems at 49.9 (5) and 73.4 (3)°. In the crystal, molecules are linked by N - H⋯O and O - H⋯O hydrogen bonds and weak C - H⋯π interactions into a three-dimensional supramolecular architecture. A void of 33.0 (7) ų is observed in the crystal structure. The solvent ethanol molecule acts as a donor, forming an O - H⋯O hydrogen bond, reinforcing the framework structure.
