Abstract

In this paper, chelate compounds of Co(II) and Cu(II) as a result of making reactions for those ions with the ligand 2-(Benzothiozolyl azo- 4- benzyl phenol has been presented. The preparing procedure for compounds has been performed by setting up the optimal concentration and pH conditions. UV-Vis investigation of the compound solutions have been examined for various pH and concentration magnitudes based on the rule of Lampert-Beers. The compound geometries can be figured out in relation to mole ratio technique that can be found by the spectroscopy identification of the compound solutions. The gotten ratios of metal: ligand has been (1:2) for every compound. Ligand detection has been done via UV-Vis and IR measurements. The measured conductivity consequences prove that the ligand has been tridentate. Furthermore, the anticipated complexes structures of Co(II) and Cu(II) ions were octahedral.
