Crystal structure and Hirshfeld surface analysis of 4-allyl-6-bromo-2-(4-chlorophenyl)-4H-imidazo[4,5-b]pyridine

Abstract

The imidazo[4,5-b]pyridine unit is planar, while the phenyl and allyl substituents are rotated a little out of this plane. In the crystal, mol­ecules are linked via pairs of the weak inter­molecular C—H⋯N hydrogen bonds, forming inversion dimers with (20) ring motifs. The dimers are further connected by π–π stacking inter­actions between the imidazo[4,5-b]pyridine ring systems.
