Abstract: | Fifteen new kinds of mixed ligand complexes Cu(x‐P)A P = 2‐(COO)C6H4CONH‐C6H4; x = H, 2‐Cl, 2‐CH3, 2‐OCH3, 4‐OCH2CH3; 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 Ea, the activation entropy δS≠, 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.
