摘要: The TG and DTA of a new series Mn(II) Cu(II) complexes with number newly prepared bisazo-dianil ligands were studied in the temperature range (20-700°C). DTG curves display to main steps, first one within (25-330°C) correspond elimination water or ethanol from complexes. second step (350-625°C) is due decomposition yielding metal oxides as final product. rate constants dehydration reactions determined, which some kinetic parameters evaluated. show that an endothermic reaction. In all cases anhydrous undergo exothermic give oxide. thermodynamic (ΔE, ΔH, ΔS, ΔG) for occurring processes are calculated. electrical conductivities solid measured activation energy complex its free ligand also
