Synthesis, characterization and antimicrobial activities of leucine-acetylacetone Schiff base and its Mn(II), Ni(II) and Cu(II) complexes

A Schiff-base derived from leucine and acetylacetone, and its Cu(II), Ni(II) and Mn(II) complexes were synthesized and analyzed based on their melting point/decomposition temperature, solubility, molar conductance, magnetic and infrared analyses. Physical and analytical data suggested that the Schiff base acted as tridentate ligand towards metal ion via azomethine-N, deprotonated-O of carboxylic group and enolic-O group of acetylacetone. All the...
