چکیده
In the zwitterionic title compound, C(18)H(17)Br(4)N(3)O(2), the two salicylaldimine groups form a dihedral angle of 51.94 (2)° and the dihedral angle between the aromatic ring planes is 51.14 (2)°. One of the C atoms adjacent to the aza N atom is disordered over two positions; the site-occupancy factors are 0.51 (1) and 0.49 (1). There are two strong intra-molecular N-H⋯O hydrogen bonds in the mol-ecule.

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.
