Abstract

In the title centrosymmetric dinuclear complex, [Cu₂(C₁₅H₁₁BrN₂O₃S)₂(C₂H₆OS)₂], the Cu^II ion is N,O-chelated by a dianionic ligand, monocoordinated by the sulfonamide N atom of a symmetry-related ligand and coordinated by an O atom from a dimethyl sulfoxide ligand, forming a distorted square-planar coordination geometry.

Experimental

The Schiff base ligand was synthesized by refluxing 5-bromo-2-hydroxyacetophenone (0.6 g, 2.8 mmol) with benzene sulfonohydrazide (0.48 g,2.8 mmol)in ethanol for 2 h. The ligand then was refluxed with Copper (II) acetate for 5 h. The brown crystal were obtained by recrystalization the product from DMSO.
