6-Bromo-2-(4-chloro-phen-yl)-3-methyl-3H-imidazo[4,5-b]pyridine

摘要

In the title compound, C13H9BrClN3, the imidazo-pyridine fused-ring system is almost planar, with r.m.s. deviation of 0.006?(19)??, and makes a dihedral angle of 29.32?(8)° with the mean plane of the 4-chloro-phenyl group. In the crystal, C—H?N hydrogen bonds link the mol-ecules into chains propagating in the [100] direction. Weak inter-molecular?π–π?inter-actions between the five- and six-membered rings of the 3H-imidazo[4,5-b]pyridine moieties of neighbouring mol-ecules [centroid–centroid distance = 3.8648?(12)??] further consolidate the packing into layers parallel to the?ab?plane.
