Synthesis, spectral characterization and antimicrobial activity of some transition metal complexes with new schiff base ligand (BDABI)

Abstract

A new Schiff base derivative ligand (LI) have been produced by condensed isatin and 2,3-diaminobutane (2:1) molar ratio. The (LI) ligand has been separated and distinguished by 1H,13C-NMR, (CHN) elemental analysis, UV-visible, mass spectroscopy and Fourier Transform infrared (FTIR) methods. The metal ions, cobalt(II), nickel(II) and copper(II) complexes were synthesized with the ligand. The complexes were typified by, UV-Visible, FTIR, atomic absorption, molar conductance, magnetic susceptibility and elemental analysis (CHN) techniques. Octahedral geometry are suggested for the metal complexes based on the results of physico-chemical and spectral techniques. The TLC for (LI) ligand and complexes demonstrated single spot for each, signifying their compounds purity. All these compounds were determined aligned with two classes of human pathogenic; bacteria Gram positive and Gram negative.
