Abstract
Cadmium(II) complexes with 3-(6H-dibenzo[b,e] thiepin-11-ylidene) propyl dimethyl amine chloride (dot) and 2-diphenyl methoxy--N,N-dimethylamine hydrochloride (dp) were synthesised and characterised by reflectance, IR, ^{1}H NMR, magnetic moments and conductivity measurements. The new complexes studied for kinetics of thermal degradation by thermogravimetric analyses (TGA) and derivative thermogravimetric studies (DTG) in a static nitrogen atmosphere at a heating rate of 10°C min^{-1}. The kinetic and thermodynamic parameters such as energy of activation (Ea), frequency factor (lnA), enthalpy (\Delta H), free energy (\Delta H), and entropy (\Delta S) evaluated. The energy of activation values for the degradation of (dot) and (dp) complexes were found to be in the range 22.3-125.4 kJ mol^{-1}.
