The complex of [La2(P-MBA)6(PHEN)2]2H2O (P-MBA: p-methylbenzoate and PHEN: 1,10-phenanthroline) was prepared and characterized by elemental analysis and IR spectroscopy. The thermal behavior of [La2(P-MBA)6(PHEN)2]2H2O in dynamic nitrogen atmosphere was investigated by TG-DTG techniques. The results show that the thermal decomposition process of the [La2(P-MBA)6(PHEN)2]2H2O occurs in five steps. The empirical kinetic model for the first-step thermal decomposition obtained by Malek method is SB(m,n). The activation energy E and the pre-exponential factor lnA for this step reaction are 76.4 kJ*mol-1 and 24.92, respectively.
