1-Benzyl-4-(4-nitrophenyl)-2,3-dihydro-1H-1,5-benzodiazepine: a three-dimensional framework structure generated by two C-H...O hydrogen bonds and one C-H...pi(arene) hydrogen bond.

In the title compound, C22H19N3O2, the seven-membered ring adopts a boat conformation. The molecules are linked by a combination of two C-H...O hydrogen bonds and one C-H...pi(arene) hydrogen bond into a complex three-dimensional framework structure; each individual hydrogen bond generates a one-dimensional substructure, and pairwise combinations of two hydrogen bonds generate a further set of three one-dimensional substructures.
