Description

The present is base on connection with the complexing behavior of 1,3,5-oxadiazole-2-thione-8-hydroxy quinoline merged molecules. Thus, it would be better to review 8-Hydroxy quinoline derivatives particularly 5-amino-8-hydroxy quinoline derivatives, 1,3,5-oxadiazole and its derivatives particularly 1,3,5-oxadiazole-2-thione derivatives, complexing agents, objectives .Complexing agents are importance in chemistry such as in gravimetric, titrimetric and colorimetric measurements. New types of Complexing agent are constantly under investigation, for possible commercial and industrial applications. The growing importance of the use of metal complexes in chemistry may be realized by the ever-increasing number of publications on this subject. G. T. Morgan and Drew scientist .first discovered CHELATE from the Greek word CHELE used for crabs claw to designate to cyclic structures which arise from the union of metallic ions with organic or inorganic molecules.
