In this study, the overall stability constants of copper(II) complexes with some β£-amino acids (glycine, DL-alanine, DL-valine, L-leucine, L-asparagine, L-glutamine) were determined by potentiometric titration in water, 25% dioxan-75% water, 35% dioxan-65% water, 50% dioxan-50% water, and 60% dioxan
Fifteen new kinds of mixed ligand complexes Cu(x-P)A [P = 2-(COO)C 6 H 4 CONH-C 6 H 4 ; x = H, 2-Cl, 2-CH 3 , 2-OCH 3 , 4-OCH 2 CH 3 ; A = dehydronium Met, Leu, Phen] were synthesized. The thermal decomposition behavior of each complex is studied by TG. Coats-Redfern, MacCallum-Tammer, and Zsako met
