The title compound was prepared by condensation of 3-bromobenzaldehyde and hydrazine hydrate in absolute ethyl alcohol and in the presence of sulfuric acid. The title Schiff base compound, C14H10Br2N2, crystallizes with one half-molecule in the asymmetric unit in P21/c monoclinic space group. The mid-point of the N-N bond (1.412(13) Å) lies on an inversion center. The molecular skeleton is approximately planar. In the crystal packing of this complex, neighboring molecules are linked to each other by H…H intermolecular interactions to form 2D sheets.
