Abstract

Complexes of the 8-((furan-2-ylmethylene)amino)naphthalene-1-amine, Schiff base ligand with the metal ions, Cr(III), Co(II), Ni(II) and Cu(II) have been prepared and characterized by elemental analyses, IR, 1H NMR, Uv-visible, magnetic moment, molar conductance and thermal analysis. The complexes are found to have the formulae [CrLCl(H2O)3]Cl2.3H2O, [CoL2(H2O)2]Cl2.3H2O, [NiL(H2O)2]Cl2.4H2O and [CuL(H2O)2]Cl2.2H2O. The conductance of complexes is measured and revealed their electrolyticnature. Thermal analysis and thermodynamic parameters of the complexes were investigated and indicated the presence of hydrated water molecules. The antimicrobial activity is assayed in vitro against two fungi and four bacteria species.
