Özet
Stability constants of Cu(IT) and Fe(III) with some aryl Schiff bases derived from salicylaldehyde and aniline, 3-hydroxy and 3-chloro anilines were determined spectrophotometrically using ''Chattopadhyaya and Singh'' method at 25 degrees C in methanol. Cu(II) form; 1:1 and 1:2 complexes, and Fe(III) forms 1:3 complexes with these Schiff bases. The order of stability constants of the ligands used for these complexes was as follows: salicylidene-3-hydroxyaniline > salicylidene aniline > salicylidene-3-chloroaniline. The effects of substituent groups on the stability constants were discussed.
