Synthesis and Identification of Nickel (ll) , Cobalt (ll) and Copper (ll) Complexes with the Organic Reagent ( Sodium – 1 – Amino – 9,10 – Dioxo – 4 – Phenylamin – Anthracene – 2 – Sulphonate )

Abstract

The complexes of Nickel (ll) , Cobalt (ll) and Copper (ll) were synthesized by using  Sodium – 1 – Amino – 9,10 – Dioxo – 4 – Phenylamin – Anthracene – 2 – Sulphonate , acid blue – 25 , ( AB25 ) reagent as a ligand . They were characterized by many techniques such as  the element analysis , IR spectroscopy and UV.VIS. spectroscopy . Their physical properties  such as  electric conductivity and magnatic properties , were determind . It was found that Nickel (ll) complex has diamagnetic properties , whereas  Cobalt (ll) and Copper (ll) complexes have paramagnetic properties . Cobalt complex did not have any conductivity , whereas  the ligand , Nickel (ll) complex and Copper (ll) complex have good conductivity . The formula of the complexes under this research were detected by using the mole ratio method which lead to the formation of ( 1:1 ) metal : ligand formula for Nickel (ll) and Copper (ll) complexes , whereas  Cobalt (ll) complex was ( 1:2) metal : ligand formula . In all the complexes the coordination was through O and N atoms of the oxo sulfate and amine groups .  the suggested geometrical shapes of the complexes were the squar pyramidal shape for Nickel (ll) and Copper (ll) complexes and octahedral for Cobalt (ll) complex .
