Phenomenological and mechanistic characteristics of the thermal decomposition of perchlorate, nitrate, thiocyanate, chloride and bromide iron(III) complexes with the Schiff base 1,2-bis(imino-4’- antipyrinyl)ethane (GA) were studied by thermo gravimetric and derivative thermo gravimetric analyses. It was observed that the counter anions may have a major effect on the thermal stability of the present complexes.The decomposition reaction mechanism is in accordance with a ‘random nucleation with one nucleus on each particle, i.e. the Mampel model’.
