Abstract :The complexes of Cuinsert ignore into journalissuearticles values(II);, Coinsert ignore into journalissuearticles values(II);, Zninsert ignore into journalissuearticles values(II);, and Cdinsert ignore into journalissuearticles values(II); with 9-ethyl-3-carbazolecarboxaldehyde 4-phenyl-3-thiosemicarbazone were synthesized and their stability constants were determined using a spectrophotometric method at different temperatures insert ignore into journalissuearticles values(25, 30, 35 and 40 \pm 0.1°C); and ionic strengths insert ignore into journalissuearticles values(0.05, 0.01 and 0.20 M KNO3); in 50% insert ignore into journalissuearticles values(v/v); aqueous DMF. From these constants, the thermodynamic stability constants and thermodynamic parameters insert ignore into journalissuearticles values(D G°, D H° and D S°); were calculated.
