N,N'-Bis(4-bromo-2-fluoro-benzyl-idene)ethane-1,2-diamine

The mol-ecule of the title Schiff base compound, C(16)H(12)Br(2)F(2)N(2), lies across a crystallographic inversion centre and adopts an E configuration with respect to the azomethine C=N bonds. The imino groups are coplanar with the aromatic rings. Within the mol-ecule, the planar units are parallel, but extend in opposite directions from the dimethyl-ene bridge. An inter-esting feature of the crystal structure is the short inter-molecular Br⋯F inter-actions [3.2347 (16) Å, which is shorter than the sum of the van der Waals radii of these atoms]. These inter-actions link neighbouring mol-ecules along the c axis. The crystal structure is further stabilized by inter-molecular C-H⋯N hydrogen bonds.
