英文摘要：

Two new oxovanadium complexes with poly（pyrazolyl）borate and carboxylic acid as ligands, VO [phCH2CH （NH2）COO] [HB（pz）3] （1） and VO（3,5-Me2pz）[HB（3,5-Me2pz）3]（CH3COO） （2）, were synthesized successfully. The two complexes were characterized by IR, elemental analyses, thermal analyses, and single crystal X-ray diffraction. The study of non-isothermal decomposition kinetics for complex 1 showed that the possible reaction mechanisms of the two steps were nucleation and growth with n=1/4, and chemical reaction, respectively; the kinetic equations may be expressed as dcddT=（A/β）e^-EIRT（1/4）（1-α）[-ln（1-α）]^-δ and dα/dT=（A/β）e-EIRT（1-α）^2, respectively, the apparent activation energies of the steps are 223.52 and 331.94 kJ.mol^-1, respectively, the pre-exponentials ln（A/s^-1） are 49.67 as well as 57.50. The study of non-isothermal decomposition kinetics for complex 2 showed： the possible reaction mechanisms of the two steps were chemical reaction, and nucleation and growth with n=1/2, respectively, the kinetic equations may be expressed as dα/dT=（A/β）e-EIRT（1-α）^2, and dα/dT=（A/β）e-EIRT（1/2）（1-α）[-ln（1-α）]^-1, respectively, the apparent activation energies of the steps were 300.56 and 444.72 kJ. mol^-1, respectively, the pre-exponentials ln（A/s^-1） were 75.53 as well as 92.50.
