Synthesis, Structural Characterization and Biocidal Studies of Manganese(II), Iron(II), Cobalt(II), Nickel(II), Copper(II), Zinc(II) and Cadmium(II) Complexes with Tridentate Schiff Bases and 2,2′- Bipyridylamine

The reaction of metal chlorides with 2-hyuroxy-1 -naphthylidene-o-aminophenol (H2SB1) or 2-hydroxy-1-naphthylideneanthranilic acid (H2SB2) in I : I molar ratio and further reaction with 2,2′-bipyridylamine in alcohol yields mixed-ligand complexes. All of these complexes are soluble in ethanol, methanol and dimethyl formamide. They were characterized on the basis of elemental analyses, magnetic measurements, infrared spectra, electronic spectra, thermogravimetric analyses. Biocidal studies have also been undertaken.
