The rare earth metal perchlorates of trivalent lanthanum, cerium and samarium were used for the synthesis of metal chelates. The Schiff base(5BA) ligand was synthesized from 5-bromo salicylaldehyde and 2-amino benzoic acid (anthranilic acid) in ethanol. The synthesized ligand plays a significant role in biological applications due to the presence of halogen atom in its chemical structure. The schiff base ligand acts as a chelating agent and it is able to form six membered ring by coordinating with metal ion through the oxygen and nitrogen donor atoms corresponding to the functional groups -OH, -COOH and -C=N groups. The synthesized metal chelates have been characterized by elemental analysis, FTIR, TGA, electronic spectra, magnetic and molar conductance. Activation energy of metal chelates was evaluated using TGA data by Broido method. The synthesized chelates were subjected to study of catalytic properties for various reactions. The catalytic study of all the chelates in organic synthesis reaction was carried out. The chemical kinetic reactions were also studied to check the effect of chelates on rate of reaction. All the chelates and Schiff base ligand were screened for antimicrobial study against gram positive (B. subtilis, B. cereus) and gram negative (E. coli, P. aeruginosa) bacterial species.
