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

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