Crystal structure of dimethyl 3,3′-[(4-chloro­phen­yl)methyl­ene]bis­(1H-indole-2-carboxyl­ate)

In the crystal, mol­ecules are linked by N—H...O hydrogen bonds, forming inversion dimers, which are linked by a further N—H...O hydrogen bond, forming chains along [100]. There are intra- and inter­molecular C—H...π inter­actions present, the latter linking the chains to form a three-dimensional supra­molecular structure.
