The aim of the present work includes the prepration of 5-sulfo-7-(p-substituated phenyl azo)-8-hydroxyquinoline ligands . The formed ligands were reacted with UO2(NO3)2 and VO22+ to form their corresponding complexes. All prepared comounds were characterized by elemental analyses and various physico-chemical techniques. The azo quinoline compounds act as a monobasic bidentate chelates through the nitrogen of azo group and alcholic oxygen of 8-hydroxyquinoline moiety. As a matter of fact, the transition metal ion complexes of hydrazone and/or azo compounds have applications as catalyst in various chemical and photochemical reactions as well as in biological systems. The 8-hydroxyquinoline applications of such metal complexes to any system depends to a great extent on its molecular structure. Thus, it is of importance to get an idea about the structure of the formed complexes. The DC electrical behaviour of 5-sulfo-7-(p-substituated phenyl azo) ...
