Microwave Preparation, Spectral Studies and Antimicrobial Activities Evaluation of Mn(II),Ni(II), Hg(II),Co(II) and Cu(II) Complexes with Schiff Base Ligand

New Schiff base and their Mn(II),Co(II),Ni(II), Cu(II) and Hg(II) complexes formed by thecondensation of O-phathaldehyde and ethylene diamine (2:1) to give ligand (L1) in the firststep ,then the ligand (L1) with 2- aminophenol (1:2) to give ligand (L2) were prepared byclassic addition through microwave method . These compounds (Ligands and complexes)have been diagnosed electronic spectra, FT-IR, 1H- 13C-NMR (only ligand), magneticsusceptibility, elemental microanalysis and molar conductance measurements. Analyticalvalues displayed that all the complexes appeared (metal: ligand) (1:1) ratio with the sixchelation. All the compounds appear a high activity versus four types of bacteria such as;(Escherichia coli), (Staphylococcus aureus),(Bacillus btilis), (Staphylococcus aureus) and(Pseudomonas aeruginosin).
