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

In the title compound C(22)H(18)BrN(3), the cyclo­pentane ring adopts an envelope conformation with the central methyl­ene C atom as the flap. The dihedral angles between the central pyridine ring and the pendant benzyl and and bromo­benzene rings are 82.65 (1) and 47.23 (1)°, respectively. In the crystal, inversion dimers linked by pairs of N—H⋯N(n) (n = nitrile) hydrogen bonds generate R (2) (2)(12) loops. These dimers are linked by weak π–π inter­actions [centroid–centroid distance = 3.7713 (14) Å] into a layered structure.
