Abstract :In this study, the synthesis of a novel N-pivot 12-membered macrocyclic ligand with mixed donor atoms 2 , which is a phthalonitrile derivative, and a new cobaltinsert ignore into journalissuearticles values(II); phthalocyanine complex 3 obtained by cyclotetramerization reaction of  2 were described.  Newly synthesized compounds were characterized by using several spectroscopic techniques such as IR, UV-Vis, 1 H and 13 C NMR, MS and elemental analysis. These macrocyclic systems 2 and 3 were investigated as extractants in liquid-liquid extraction technique to reveal metal ion binding capability towards transition metals such as Aginsert ignore into journalissuearticles values(I);, Hginsert ignore into journalissuearticles values(II);, Cdinsert ignore into journalissuearticles values(II);, Zninsert ignore into journalissuearticles values(II);, Cuinsert ignore into journalissuearticles values(II);, Niinsert ignore into journalissuearticles values(II);, Pbinsert ignore into journalissuearticles values(II); and Coinsert ignore into journalissuearticles values(II);. The highest extractability from aqueous phase to organic phase was found for Hginsert ignore into journalissuearticles values(II); cation over the other metal cations with cobaltinsert ignore into journalissuearticles values(II); phthalocyanine 3 . The extraction percentage of Hginsert ignore into journalissuearticles values(II); cation from aqueous phase to chloroform in the presence of cobaltinsert ignore into journalissuearticles values(II); phthalocyanine 3 as extractant was found as 96.0%.
