Abstract
Abstract Three transition metal perchlorate complexes of general formula [M(dah)2)](ClO4)2 (where M = Zn, Cu, and Ni; dah = 1,6-diaminohexane) have been prepared, and characterized by elemental analysis, infrared spectroscopy (IR), and gravimetric method. The thermal decomposition has been studied by thermogravimetry (TG), differential thermal analysis (DTA), and differential scanning calorimetry (DSC). Kinetics parameters of their thermolysis were evaluated by model-fitting and isoconversional methods using isothermal TG data. Model-fitting method has given the single value of activation energy (E) whereas; isoconversional method yields a series of E values which vary with the extent of conversion. Further ignition delay of these complexes was measured to see the response toward rapid heating with varying amounts. The thermal stability of the complexes decreases in the order as: [Zn(dah)2)](ClO4)2 > [Cu(dah)2)](ClO4)2 > [Ni(dah)2)](ClO4)2
