Abstract

The title compound, C23H21N3, comprises a 2-amino-3-cyano-pyridine ring fused with a cyclo-pentane ring. The later adopts an envelope conformation with the central methyl-ene 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, mol-ecules are linked by pairs of N-H⋯Nnitrile hydrogen bonds, forming inversion dimers with an R 2 (2)(12) ring motif. The dimers are linked by C-H⋯π and π-π inter-actions [centroid-centroid distance = 3.7211 (12) Å], forming a three-dimensional framework.
