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, C 14 H 10 Br 2 N 2 , crystallizes with one half-molecule in the asymmetric unit in P 2 1 / c monoclinic space group. The mid-point of the N-N bond (1.412(13) A) 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. INTRODUCTION Schiff bases have received more attention in recent years due to various promising applications such as antimicrobial, 1-2 antifungal, 3 antitumor reagents. 4 Moreover, Schiff bases are used as substrates in the preparation of number of industrial and biologically active compounds via ring closure, cycloaddition and replacement reactions. Schiff bases have also been employed as ligands for complexation of metal ions.
