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 methods are adopted to estimate the values of the apparent activation energy E a , the activation entropy δ S ≠ , the reaction order n , and the frequency factor A . The results showed that the reaction order is 2/3 for each of the complex. Studies on the mechanism of the thermal decomposition reactions suggested that these reactions all fit the kinetic equation 1 − (1 − α) 1/3 = © 2003 Wiley Periodicals, Inc.
