Abstract

In the title compound C22H18BrN3, 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 bromo-benzene rings are 82.65 (1) and 47.23 (1)°, respectively. In the crystal, inversion dimers linked by pairs of N - H⋯Nn (n = nitrile) hydrogen bonds generate R22(12) loops. These dimers are linked by weak π-π interactions [centroid-centroid distance = 3.7713 (14) Å] into a layered structure.
