| Abstract | ||
| This work involves synthesis of ligand 2-(1,3-benzothiazol-2-yl thio) phenyl aceto hydrazide by the reaction of 2-mercapto benzothiazole (2-MBTH)with potassium hydroxidein an ethanolic solution(1). The product was reaction with ethyl chloro acetate in the same solution and the product reacted with phyenyl hydrazine as following condensation product. And this work prepared sever complexes of this ligand with number of metals. These complexes synthesized from the reaction of ligand with metal ions [Cr(III),Mn(II),Co(II),Ni(II),Cu(II),Zn(II) ,Cd(II) ] Elemental analysis . Infrared spectroscopy , UV – visible spectroscopy, atomic absorption, magnetic susceptibility, molar vatio and molar conductance measurements have been determined. I t was concluded from the elemental analysis that all the complexes have (1:1) ( ligand : metal ) mole ratio but Cr(III)(2:1) that make bridge band between two ligands . Evidence from IR spectra shows that all complexes the ligand is coordinated via the thizole nitrogen, oxygen and exocyclic sulfur atom. | ||
