title: 5-Bromo-1H-pyrrolo-[2,3-b]pyridine.
abstract: In the title compound, C7H5BrN2, fused six-membered pyridine and five-membered pyrrole rings form the essentially planar aza-indole skeleton (r.m.s. deviation = 0.017 Å). In the crystal, pairs of N-H⋯N hydrogen bonds connect the mol-ecules into inversion dimers.
