| Abstract: | The synthesis of a Cu (Ⅱ) complex with 2-picolinic acid (Hpic) was described. The magnetic properties and thermal behaviors were studied. The complex showed excellent magnetic properties. The kinetic analysis of the title complex indicated that the main reaction of thermal decomposition was a single-step reaction and the kinetic equation can be expressed as: dα/dt＝A (1-α)n·αa·exp(-E/RT). |
