摘要

The title ternary complex Nd[(C5H8NS2)3(C12H8N2)] has been synthesized in absolute ethanol by the reaction of atmosphere without any cautions against moisture. The bonding characteristics of the complex were characterized by IR, showing that Nd3+ is bonded with sulfur atom in the APDC and coordinated with nitrogen atom in the phen.TG-DTG investigation indicates that the title complex was decomposed into Nd2S3 and deposited carbon in one step where Nd2S3 predominated in the final products. The enthalpy change of formation of the reaction on the title complex in liquid-phase has been determined by a microcalorimeter. Thermodynamic parameters (the activation enthalpy, the activation entropy and the activation free energy) and kinetics parameters (the rate constant, the apparent activation energy, the pre-exponential constant and the reaction order) of the title reaction have been calculated. The enthalpy change of the solid-phase reaction has been obtained by a thermochemistry cycle.
