| Abstract | ||
| The aim of this work is synthesis and characterization of the tridentate Schiff base ligand (HL) containing (N and O) as donor atoms type (ONO. (HL) phenyl 2-(2- hydroxybenzylidenamino)benzoate This ligand was prepared by the reaction of (phenyl- 2-aminobenzoate) with salicylaldehyde under reflux in ethanol and few drops of glacial acetic acid which gave the ligand (HL). The prepared ligand was characterized by (FT IR,UV-Vis) spectroscopy. Elemental analysis of carbon, hydrogen and nitrogen (C.H.N.) and melting point. The ligand was reacted with some metal ions under reflux in ethanol with (1 metal :2 ligand )mole ratio which gave complexes of the general formula: [M(L)2] , M = MnII,FeII ,CoII,NiII,CuII, ZnII , PdII,CdII,HgII The Products were found to be solid crystalline complexes, which have been characterized through the following techniques: Molar conductivity .Spectroscopic method [FTIR and UV-Vis], additional measurement magnetic susceptibility, Chlorid content and Program [Chem office-CS. Chem.-3D pro 2006)was used. Our research also includes studying the bio-activity of the some compounds prepared against a kind of bacteria three of which were negative to gram dye (Proteus mirabilis, Klebsiella pneumonia, Escherichia coli), and one was positive to gram dye (Staphylococcus aureus). Some of the compound showed inhibitive activity against some of bacteria under consideration. The magnetic moment coupled with the electronic spectra suggested an octahedral geometry for all the complexes. | ||
