Crystal structure of 2-benzyl­amino-4-p-tolyl-6,7-di­hydro-5H-cyclo­penta­[b]pyridine-3-carbo­nitrile

The title compound, C(23)H(21)N(3), comprises a 2-amino-3-cyano­pyridine ring fused with a cyclo­pentane ring. The later adopts an envelope conformation with the central methyl­ene C atom as the flap. The benzyl and and p-tolyl rings are inclined to one another by 56.18 (15)°, and to the pyridine ring by 81.87 (14) and 47.60 (11)°, respectively. In the crystal, mol­ecules are linked by pairs of N—H⋯N(nitrile) hydrogen bonds, forming inversion dimers with an R (2) (2)(12) ring motif. The dimers are linked by C—H⋯π and π–π inter­actions [centroid–centroid distance = 3.7211 (12) Å], forming a three-dimensional framework.
