摘要：

The complex of [Tb-2(p-ClBA)(6)(PHEN)(2)] [(p-ClBA: p-chlorobenzoate and PHEN: 1,10-phenanthroline) was prepared and characterized by elemental analysis and IR spectroscopy. The thermal behavior of [Tb-2(p-ClBA)(6)(PHEN)(2)] in dynamic nitrogen atmosphere was investigated by TG-DTG, SEM and IR techniques. By the kinetic method of processing thermal analysis data put forward by Malek et al., it is defined that the kinetic model for the first-step thermal decomposition is SB(m,n). The activation energy E and the pre-exponential factor lnA for this step reaction are 164 kJ mol(-1) and 32.80, respectively. The lifetime equation at mass loss of 10% was deduced as lntau=-33.0569+20512.36/T by isothermal thermogravimetric analysis.
