Spectroscopic, thermal analysis and antimicrobial activities of supramolecular Cu (II) complexes

A series of Cu (II) complexes of azo dye ligands 4-(4-hydroxy-5-(aryldiazenyl)-2-
thioxothiazol-3 (2H)-yl) benzenesulfonamide (HL n) were synthesized by the coupling of 3-
sulfamoylphenylrhodanine with aniline and its p-derivatives. These ligands and their [Cu (L 
n)(CH 3 COO)(OH 2)] H 2 O complexes were characterized by elemental analyses, IR, 1 H 
NMR, UV–Visible and magnetic measurements as well as thermal analysis and X-ray 
diffraction.
