The crystal structure of the title compound, C12H9BrN4O2, shows that the stereochemistry about the N=N double bond in the diazoamine moiety is trans. The dihedral angle [6.7(6)°] between the terminal phenyl rings indicates that the whole molecule is almost planar (r.m.s. deviation = 0.0945 Å). Intermolecular N-H…O and C-H…O hydrogen bonds generate infinite one-dimensional linear chains along the [0 0 1] direction. The unequal distribution of the double-bond character among the N atoms of the diazoamine moiety indicates a delocalization of the π electrons over the N=N-N(H) moiety towards the terminal aryl substituents.
