6-Bromoimidazo[1,2-a]pyridin-8-amine

The title compound, C7H6BrN3, crystallizes with three independent molecules in the asymmetric unit. The molecules are approximately planar (r.m.s. deviations for all non-H atoms = 0.016, 0.023 and 0.024 Å). The primary amine groups show pyramidal coordination. In the crystal, adjacent molecules are linked by N—H...N hydrogen bonds. For two independent molecules, the amine groups are hydrogen-bond donors via one H atom to one acceptor atom, whereas for the third independent molecule, the amine group is a hydrogen-bond donor to two acceptor atoms.
