Abstract :

New Schiff base transition metal complexes have been synthesized via the condensation of 3-amino-5-omobenzofuran-2-carboxamide and Salicylaldehyde. Tentative structures for the synthesized complexes have been elucidated on the basis of analytical, elemental, UV-VIS, IR, ¹HNMR, ESR and Mass spectral studies. All the complexes are soluble in DMF and DMSO. The measured molar conductance values suggest that the complexes are non-electrolytic in nature. We propose the octahedral geometry for Co(II), Ni(II) and Cu(II) complexes, based on electronic spectral data, magnetic data and ligand field parameters. The Cd(II), Zn(II) & Hg(II) complexes show the tetrahedral geometry. The Schiff base and their metal complexes were screened for their anti-bacterial, anti-fungal and DNA cleavage activities.
