Synthesis and Characterization of 4-(3-bromo-5-chloro-2-hydroxybenzlidimino) Benzoic Acid and its Transition Metal Complexes

P. Gopu | Dr. A. Xavier

Abstract: Metal complexes using the schiff base ligand of 3-bromo-5-chloro salicylaldimino-4-amino benzoic acid have been prepared and characterized by elemental analysis, magnetic and spectroscopic measurements viz. , (infrared and 1H-NMR). An elemental analysis of the metal complexes was suggested that the stoichiometry of metal-Ligand ratio is 12. The following first row transition metals are used in our studies namely Co (II), Cu (II), and Mn (II). The coordination of metals with ligand were identified by Fourier transform infra red spectroscopy. The geometry of complexes were detected by the electronic spectroscopy. The proposed geometry for Mn-L1complexes is octahedral geometry. Other Co (II) and Cu (II) complexes are distorted octahedral geometry.
