SYNTHESIS, CHARACTERIZATION AND PRELIMINARY ANTIMICROBIAL STUDIES OF SOME SCHIFF BASE LIGANDS AND THEIR Co(II), Mn(VII), Mo(VII) COMPLEXES

📄 Project Abstract

The synthesis, characterization and preliminary antimicrobial studies of some novel Schiff base ligands; N,N/ - Bis(2-hydroxybenzylidene)-1,4-phenylenediimine(M) and N,N/ - Bis(4-dimethylaminobenzylidene)-1,4-phenylenediimine (N) were undertaken. It was prepared by the condensation reaction of 1,4-phenylenediamine with 4-dimethylaminobenzadehyde and 2-hydroxybenzaldehde .Their Co(II), Mn(VII), Mo(VII) metal complexes were synthesized by coupling them respectively with the individual formed ligands. These ligands and their complexes were characterized on the basis of their melting point, stoichiometry, electronic spectra, infrared spectra and antimicrobial their antimicrobial properties. Spectrophotometric analysis gave the stoichiometry to be 1:1 metals to ligand mole ratio for the Co(II) and Mn(VII) complexes of the N,N/ - Bis(2-hydroxybenzylidene)-1,4-phenylenediimine(M) ligand and a 1:2 metal to ligand mole ratio for its Mo(VII) complex. Secondly its N,N/ - Bis(4-dimethylaminobe...
