The thermal behaviors of the complexes of CU(DMTZB) 4 X 2 (DMTZB=3,3′‐dimethyl‐1‐(1 H ‐1,2,4‐triazol‐1‐yl)‐2‐butanone, X=NO 3 or ClO 4 ) and CU(DMTZB) 2 X 2 (X=Br or Cl) in a nitrogen atmosphere were studied under the non‐isothermal conditions by simultaneous TG‐DTG‐DSC. EDS and elemental analysis techniques. The results showed that their decomposition proceeded in three different ways mainly depending on the anions in the molecules. The heat effect associated with the decomposition step of DMTZB molecules was also different. The decomposition mechanisms and the kinetic parameters of DMTZB were determined and calculated by jointly using four methods, which showed that its pyrolysis was controlled by D3 mechanism but with different activation energies and pre‐exponential factors for different complexes.
