2,4-Dibromo-6-[(E)-({3-[(E)-(3,5-dibromo-2-oxidobenzyl-idene)aza-nium-yl]-2,2-dimethyl-prop-yl}iminium-yl)meth-yl]phenolate.

In the title mol-ecule, C(19)H(18)Br(4)N(2)O(2), the dihedral angle between the benzene rings is 73.9 (2)°. Two intra-molecular N-H⋯O hydrogen bonds make S(6) ring motifs. In the crystal, mol-ecules are linked via C-H⋯O inter-actions, forming chains propagating along the a-axis directon. A short C⋯Br [3.401 (5) Å] contact is present in the crystal structure, which is further stabilized by a π-π inter-action [centroid-centroid distance = 3.739 (3) Å].
