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

In the title compound, C(27)H(21)N(3)O(6)·C(2)H(5)OH, 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) Å(3) 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.
