Synthesis, Crystal Structure, and Thermal Decomposition Kinetics of the Sm3+ Complex with p-Chlorobenzoic Acid and 2,2'-Bipyridine
A dinuclear samarium(III) complex [Sm(p-ClBA)(3)bipy center dot H2O](2) [p=ClBA = p-chlorobenzoate; bipy = 2,2'-bipyridine] has been synthesized and characterized by elemental analysis, molar conductance, UV and IR spectra, and TG-DTG techniques. Single-crystal X-ray diffraction analysis revealed that each Sm3+ ion in the compound is eight-coordinated with the bicapped triangular prism geometry. The crystal belongs to the triclinic system, space group P (1) over bar. The thermal decomposition behavior of the title complex in a static air atmosphere was investigated by TG-DTG and IR techniques. Meanwhile, the nonthermal kinetics of the second decomposition stage Was also Studied by using a double equal-double steps method and the nonlinear integral isoconversional method.
