Abstract :In this study, the Schiff base 2-[4-Dimethylaminocinnamalamino]- benzoic acid [insert ignore into journalissuearticles values(CH3);2N.C6H4.CH:CH.N.C6H4.COOH] insert ignore into journalissuearticles values(DACAB); was prepared by the reaction of 2-Aminobenzoic acid with p-Dimethylaminocinnamaldehyde. The protonation constants of the ligand were determined in a 50% insert ignore into journalissuearticles values(v/v); dioxane - water medium using the Irving-Rossotti and PKAS-BEST computer methods. The complexes of Feinsert ignore into journalissuearticles values(III);, Coinsert ignore into journalissuearticles values(II);, Niinsert ignore into journalissuearticles values(II);, Cuinsert ignore into journalissuearticles values(II); with DACAB were synthesized and the structures of these complexes were elucidated by means of data obtained from elemental analysis, using IR, 1H-NMR methods. The magnetic properties of the solid complexes were measured.
