β¦ Synopsis
The molecular skeleton of the title Schiff base compound, C 13 H 8 Br 2 INO, is essentially planar due to an intramolecular N-HΓ Γ ΓO hydrogen bond; the two aromatic rings make a dihedral angle of 4.4 (5) . The crystal packing exhibits short intermolecular IΓ Γ ΓBr contacts of 3.7226 (16) A Λ.
