Based on the synthesis of bis (β-diketo) vanadyl (Ⅳ) and nitrogenous base adduct, the thermal decomposition process was further studied by TG method. The kinetic parameters of the decomposition reaction were calculated and the reaction mechanism was established. Vo (bza) _2Py, VO (bza) _2γγ-MP, Vo (bza) _2iso-q (bza: benzoylacetone, Py: pyridine, γ-MP: γ- picoline, iso-q: isoquinoline) For the R_3 mechanism, VO (bza) _2Mor, Vo (bza) _2β-MP, VO (tta) _2iso-q (Mor: morpholine, β-MP: β-picoline, tta: Acetone) as the mechanism of R_2, VO (tta) _2Mor, VO (tta) _2Py as F_3 mechanism, and the relationship between the decomposition temperature and activation energy of the complexes and the vibrational frequency of v_V = 0 was discussed.
