Abstract: A new divalent mixed ligand Schiff base and some lanthanide (III) complexes such as La (III), Pr (III), Ce (III), Nd (III), Gd (III) Sm (III), Dy (III) and Tb (III) complexes were synthesized derived from condensation of salicylaldehyde with 4-methoxyphenylamine and 2-hydroxy-3-methoxybenzaaldehyde with 4-methoxyphenylamine in alcoholic medium forming 2- (E) - [4-methoxybenzylideneamine] phenol (L1) and 2- (E) - [ 4-methoxyphenylimino methyl] -6-methoxy phenol (L2) respectively. The synthesized mixed ligands and lanthanide (III) complexes were characterized by elemental analysis, FTIR, 1HNMR, UV-visible and molar conductance, x-ray diffraction, magnetic susceptibility and antimicrobial studies. These analytical and spectral data revealed that ligand coordinates with central lanthanide (III) ions by its two imines nitrogen atoms and two phenolic oxygen atoms and two water molecule the general formula of the complex is [LnL1 & L2 (H2O) 2 NO3]. The ligand metal complex obtained by (111) ( L1 metal L2) molar ratio. The result obtained by antibacterial, antifungal activity indicates that the antifungal are highly biologically active Aspergillus Niger at 500 ppm and at 250 ppm against Fusarium Oxysporum than that of antibacterial activity. All the complexes showed low conductivity i. e. Non electrolytic behavior in nature.
Keywords: Mixed ligands, antibacterial and antifungal activity, x-ray diffraction studies
