Synthesis, Characterization and Antimicrobial Activity of Schiff Base ( E)- N -(4-(2-Hydroxybenzylideneamino) Phenylsulfonyl) Acetamide Metal Complexes

Abstract

New series of Ag, Cd(II), Ce(III), Co(II), Cr(III), Fe(III), Ni(II) and Pb(II) complexes with (E)-N-(4-(2- hydroxybenzylideneamino) phenylsulfonyl) {S.S} have been synthesized. These compounds have been characterized by different physico-chemical techniques like, melting point, elemental analysis, FT-IR, UV spectroscopy, 1H NMR spectroscopy, conductance measurements, magnetic susceptibility and mass spectral analysis. The metal ions concentrations have been determined using inductively coupled plasma mass spectrometry (ICP-MS). Spectroscopic studies suggest coordination most of complexes in a regular octahedral arrangement in 2L:1M molar ratio by two N azomethine and two OH phenolic from Schiff base {S.S} in the form of [ML2(H2O)2], M metal, L ligand {S.S}. Complexes have been screened for their antibacterial {Gram negative bacteria (Escherichia coli and Pseudomonas aeruginosa)}, {Gram positive bacteria (Bacillus subtilis and Sterptococcus pneumoniae)} and antifungal (Aspergillus fumigates and Candida albicans) showing promising antimicrobial biological activity.
