Three mononuclear complexes were synthesized and characterized by elemental analysis, molar conductance and IR spectra. The thermal decomposition kinetics of Cu (Ⅱ) complexes of N, N’-bis (amino) oxalamide with Cu (Ⅱ) were studied by dynamic gravimetric and differential thermal techniques under dynamic air. The non-isothermal kinetic data were analyzed by Achar method and Coats-Redfen method, and the most suitable thermal decomposition kinetic model was proposed according to the kinetic parameters. From the thermogravimetric curves, the activation energy, enthalpy and pre-exponential factor of the thermal decomposition reaction were calculated. (Ⅱ), N, N’-bis (2-aminopropyl) oxalamide copper (Ⅱ) and N, N’-bis-3- The initial decomposition temperature of copper (Ⅱ) was as follows: Cu (oxpn)> Cu (oxap)> Cu (oxen)
