Molecules of the title compound, C7H2Br2ClN (RNC), are bisected by a mirror plane that passes through the chloro and isocyano groups. The isocyano C atom is bisected by two NC⋯Br contacts, one per Br atom. The resulting centric R22(10) rings form ribbons along , which align to form a nearly planar sheet structure that is very similar to the sheets observed in several related 2,6-dibromophenyl cyanides and isocyanides. The crystal of RNC is isomorphous with the corresponding cyanide, with solely translational stacking between sheets. This is in contrast to the 2,4,6-tribromophenyl cyanide and isocyanide, which occur as different polytypes.
