SYNTHESIS , CHARACTERIZATION AND BIOLOGICAL ACTIVITY FOR BINUCLEAR COMPLEXES Co(II), Cu(II), Ni(II), Mn(II) and Hg(II) WITH SCHIFF BASE LIGAND TYPE N2O2
Journal Title: Asian J of Pharm Sci & Tech - Year 2015, Vol 5, Issue 3
Abstract
ABSTRACT The syntheses of some Ni(II),Co(II), Cu(II),Mn(II)and Hg(II) Schiff base complexes have been reported. The Schiff base ligand H2L (C28H20N2O2) under were prepared by the condensation of amine namely benzidine with salicyladehyde. Schiff base ligand and their complexes have been subjected to elemental analysis, Infrared, electronic, nmr and 13C spectral studies, molar conductivity, and magnetic moment measurements. All the complexes showed an octahedral geometries with the general structure[M2(L)2(H2O)4]. In addition, the analysis exhibited a different chelation mode towards metal and ligand substitution, since a mono- and dinuclear metal complexes have been identified. The ligand and its complexes exhibited biological activity against the Bacillus (G+) strain and the Pseudomonase (G-) strains. Key words: Synthesis; Characterization, Schiff base, Benzidine; Ni(II),Co(II),Cu(II),Mn(II)and Hg(II) ions; binuclear complexes.
