Synthesis, Characterization, Biological and Antioxidant estimation of Mixed Schiff Base Ligand and Heterocyclic Compound with Some Metal ions

Abstract

In this research, a group of complexes were prepared which were derived from Schiff base ligands, which is called (1E,1'E)-1,1'-(1,2-phenylene)bis(N-(2,4-dichlorophenyl) methanimine) (L) with ortho-phenanthroline (o-phen). The prepared complexes are M(II) [Co(II),Ni(II),Cu(II), Zn(II), Cd(II),and Hg(II)]. A range of spectroscopic and technical techniques have been used to characterize these materials, including: The FTIR, 1H-NMR, LC-Mass Spectrum, UV-Visbale, molar conductance, and magnatic moment, atomic absorbtion, chlorid contents. Spectral results obtained are showen that (ortho-phen) and (L) behave as neutral coordinating to the central metal ion by the donating atoms (N2) of the both compounds. The geometry shape of the mono ligand (L) complexes were tetrahedral, while the geometry shape of mixed ligands (L) as first ligand with (ortho-phen) as second ligand were octahedral geometry. The antimicrobial activities of the prepared compounds were experienced by using disc diffusion process touching different types of selected bacteria; two gram positive and two gram negative, and one type of fungi.
