Abstract

Thermal decomposition of ammonium tris (malonato) ferrate (III) tetrahydrate, i. e. (NH₄)₃[Fe(CH₂C₂O₄)₃]·4H₂O has been studied up to 973 K in static air atmosphere employing Mössbauer and infrared spectroscopies, and non-isothermal techniques (TG, DTG, DTA). The anhydrous complex decomposes into an iron (II) intermediate at 453 K. The iron (II) species on further heating is reoxidized to -Fe₂O₃ as the final thermolysis product. An increase in particle size of -Fe₂O₃ with increasing decomposition temperature has been observed. The results are compared with the analogous oxalate complex.
