چکیده
The asymmetric unit of the title compound, C(16)H(12)Br(4)N(2)O(2), comprises half of a potential tetra-dentate Schiff base ligand. The whole mol-ecule is generated by an inversion center located in the middle of the C-C bond of the ethyl-ene segment. There are intra-molecular O-H⋯N hydrogen bonds making S(6) ring motifs. In the crystal, no significant inter-molecular inter-actions are observed.
