The room-temperature reaction of propargyl bromide and 6-bromo-1,3-dihydro-imidazo[4,5-b]pyridin-2-one in dimethyl-formamide yields the title compound, C(12)H(8)BrN(3)O, which features nitro-gen-bound propynyl substituents. The imidazopyridine fused ring is almost planar (r.m.s. deviation = 0.011 Å); the propynyl chains point in opposite directions relative to the fused ring. One acetyl-enic H atom is hydrogen bonded to the carbonyl O atom of an inversion-related mol-ecule, forming a dimer; adjacent dimers are linked by a second acetyl-ene-pyridine C-H⋯N inter-action, forming a layer motif.
