Abstract
N-anilinoacetohydrazo benzoylacetone (H 2 L) and their manganese (II), cobalt(II), nickel(II), copper(II) and zinc(II) complexes have been synthesized and characterized by IR, electronic spectra, molar conductivities and magnetic susceptibilities .Binuclear complexes with molar ratios of( 2:1) (M:L) are formed. IR spectra show that the ligand (H 2 L) coordinated to the metal ions in a tetradentate manner with O 2 N 2 doner sites in Mn(II),Co(II),Ni(II) andZn(II) complexes while Cu(II) complexes the ligand coordinated as didentate via NO . The electronic absorption spectra and magnetic susceptibility measurements show that all the complexes were separated as octahedral structure.T he copper (II) complexes shows higher antibacterial activity towards G+ve bacteria (Bacillas subtilis ) than the ligand and other complexes while Mn (II) complex shows higher antifungal activity.
