Microwave Assisted Synthesis Characterization and Biological Evolution of 3d- series Metal Complexes with Amide Ligands

Abstract: This study discussion the microwave synthesis, spectral, Characterization and anti microbial study of the complexes of Mn, Co, Ni and Cu with amide ligands. The complexes have been characterized on the basis of elemental analysis, IR, UV and magnetic susceptibility studies. Antibacterial activities of these ligands and complexes have also been reported on S. aureus and E.coli microorganisms. Antibacterial activities have carried out by disc diffusion method. The diffuse reflectance spectrums of the transition metal Mn(II) complexes show bands in the region 17636 cm-1 to 26881cm-1, assignable to 6A1g→4T2g, 6A1g→4Eg, 4A1g (4G) transitions. These are also typical of tetrahedral environment around the Manganese. The magnetic moment (5.79-5.92 BM) of the complex indicates high tetrahedral environment and Co, Ni and Cu metal complexes are in distorted Octahedralin environment. The green method of synthesis of these complexes carried out by green microwave bioreactor (GMBR). This method is easily, appropriate and eco-friendly.
