Crystal structure of bis(μ(2)-4-bromo-2-[({2-[({2-[(5-bromo-2-oxidobenzylidene)amino]ethyl}sulfanyl)sulfonyl]ethyl}imino)methyl]phenolato)dicopper(II) dimethylformamide disolvate

The title dinuclear copper(II) complex [Cu(2)(C(18)H(16)Br(2)N(2)O(4)S(2))(2)] was prepared by direct synthesis of a dianionic Schiff base derived from 5-bromo­salicyl­aldehyde and cyste­amine. The discrete mol­ecules lie across inversion centers and crystallize with two di­methyl­formamide (DMF) mol­ecules of crystallization. The unique Cu(II) ion is four-coordinated by two tetra­dentate Schiff base ligands in a distorted square-planar N(2)O(2) environment. In the crystal, short inter­molecular S⋯Br contacts, weak C—H⋯O hydrogen bonds and intra- and inter­molecular π–π stacking inter­actions between rings of the ligand link the components into a two-dimensional network parallel to (010).
