Abstract :In this work, a hard model chemometric method was used to determine the stability constants of copperinsert ignore into journalissuearticles values(II); and mercuryinsert ignore into journalissuearticles values(II); complexes with the newly synthesized ligand 5-insert ignore into journalissuearticles values(2-hydroxybenzylidene);- 2-thioxodihydropyrimidine-4,6insert ignore into journalissuearticles values(1H,5H);-dione in acetonitrile by UV-Vis spectrophotometry. The ligand forms stable complexes with both metal cations. The protonation constants of the ligand were also measured in an ethanol-water insert ignore into journalissuearticles values(1:1); mixture.
Keywords : Cu II, and Hg II, complexes, 5 2 hydroxybenzylidene, 2 thioxodihydropyrimidine 4, 6insert ignore into journalissue
