Abstract

The thermal analysis of acetate clusters of general formula [Fe III2 MIIO(CH3COO)6(H2O)3]·2H2O, with M=Mn, Fe, Co or Ni, was performed in dynamic and quasi-isothermal regimes. The thermal decompositions of these compounds proceed in the interval 40–310° and consist of two endothermic and three exothermic stages. Dependence on the nature of the transition metal M is evidenced most explicitly in the parameters of the second stage, proceeding in the interval 103–170°. For this stage the sequences of thermodynamic stability and kinetic stability were established. The effect of the nature of the metal on the thermodynamic and kinetic parameters of the thermal decomposition processes involving the heteronuclear acetates was analyzed. Mechanisms for the first two stages of thermal decomposition are suggested.

Zusammenfassung

Die thermische Analyse von Acetatclustern der allgemeinen Formel [Fe III2 MIIO(CH3COO)6(H2O)3]·2H2O (M=Mn, Fe, Co, Ni) wurde unter dynamischen und quasiisothermen Bedingungen ausgeführt. Die thermische Zersetzung dieser Verbindungen verläuft im Bereich von 40–310 °C in zwei endothermen und drei exothermen Schritten. Die Abhängigkeit von der Natur des Übergangsmetalls M ist bei den Parametern des zwischen 103 und 170 °C verlaufenden zweiten Schrittes am ausgeprägtesten. Für diesen Schritt wurde die Reihenfolge der thermodynamischen und kinetischen Stabilität festgestellt. Der Effekt der Natur des Metalls auf die thermodynamischen und kinetischen Parameters der Zersetzungsprozesse von heteronuklearen Acetaten wurde analysiert. Für die ersten zwei Schritte der Thermolyse werden Mechanismen in Vorschlag gebracht.

Резюме

В динамическом и кваз иизотермическом реж имах проведен термически й анализ ацетатных кластеров общей формулы [Fe III2 MIIO(CH3COO)6(H2O)3]·2Н2О, где M=Mn, Fe, Co, Ni. Процесс термолиза эт их соединений протек ает в интервале 40–310 °? и состо ит из двух эндотермических и тр ех экзотермических с тадий. Наиболее явная завис имость от свойств центрального атома п ереходного металла M обнаруживается для п араметров второй ста дии термолиза, протекающ ей в интервале 130–170°. Для этой стадии построены ряд ы термодинамической устойчивости и кинет ической лабильности. Проанализировано вл ияние природы металла на термодина мические и кинетичес кие параметры процессов термической деструк ции гетероядерных ацета тов. Предложен механи зм двух первых стадий термол иза.
