摘要：
Two new complexes [Sm(o-NBA)(3)bipy](2)center dot 2H(2)O (1) and [Sm(o-BrBA)(3)bipy](2)center dot 2H(2)O (2) (where o-NBA is o-nitrobenzoic acid, o-BrBA is o-bromobenzoic acid, and bipy is 2,2'-bipyridine) were prepared and characterized by elemental analysis, IR, UV, and molar conductance, respectively. The thermal decomposition behaviors of the two complexes were investigated by means of TC-DTG and IR techniques. The thermal decomposition kinetics was studied by using advanced double equal-double steps method, nonlinear integral isoconversional method, and nonlinear differential isoconversional method. The kinetic parameters of the second-step process for the two complexes were obtained, respectively. (C) 2008 Wiley Periodicals, Inc.
