The crystal structure of the title compound, C12H7Br4N3, shows that the stereochemistry about the N=N double bond of the N=N-N(H) moiety is trans. The whole molecule deviates slightly from planarity (r.m.s. deviation 0.164 Angstrom). While one of the aryl substituents is almost coplanar with the triazene chain, weak intermolecular Br...C contacts cause the second aryl substituent to deviate by an angle of 9.1 (8)degrees from the plane defined by the N=N-N group. Weak intermolecular N-H...Br interactions between molecules related by the diagonal glide plane give rise to chains, which are stacked along the [100] crystallographic direction. An unequal distribution of double-bond character between the N atoms suggests a delocalization of pi electrons over the diazoamino group and the adjacent aryl groups.
