چکیده
The asymmetric unit of the title compound, C(28)H(22)Br(2)N(2)O(2)S(2), comprises half of a Schiff base ligand, the whole mol-ecule being generated by a crystallographic inversion center located at the mid-point of the C-C bond of the central methyl-ene segment. Intra-molecular O-H⋯N and O-H⋯S hydrogen bonds make S(6) and S(5) ring motifs, respectively. In the crystal, there are no significant inter-molecular inter-actions.
