Abstract :
The IR, far-IR, Raman and Mössbauer spectra have been utilized to identify a new compound consisting of a tetrachloroferrate(III) anion and a tetrabutylammonium cation [(C4H9)4N][FeCl4]. Its degradation has been studied by thermal analysis using TG, TG–MS, DTG and DTA, as well as DSC techniques. The measurements were run in static air and in argon atmosphere. Solid residues were identified by elemental analysis, far-IR and Mössbauer spectroscopy. The discussion was focused on processes proceeding during the first step of the thermal decomposition.
