Abstract  

Thermal decomposition of tetrabutylammonium bromotrichloro-, tribromochloro-and tetrabromoferrates(III), of general formula [(n-C 4H9)4N][FeBr4−nCln] (n = 0, 1, 3), has been studied using the TG-MS, DTA, DTG as well as DSC techniques. The measurements were carried out in an argon atmosphere over the temperature range 293–1073 K. Solid products of the thermal decomposition were identified by X-ray powder diffractometry.

Five new derivatives of general formula [Ru(dipy)3]MCl4, whereM=Cu(II), Zn(II), Mn(II), Fe(II) and Co(II), and [Ru(dipy)3][FeCl4]2 were synthesized, and their compositions and structures were confirmed by chemical analysis and electron absorptionüspectroscopy. The thermal decompositions of the compounds were studied by thermoanalytical methods. All these complexes decompose upon heating up to 1300 K, with simultaneous loss of organic fragments and structures were confirmed by chemical analysis and electron absorption spectroscopy.The exothermic effects. The residues after heating correspond to RuO2 and the appropriate M oxides, contaminated in some cases by pure metal.

Abstract  

Thermal decomposition of compounds consisting of tetrahalogenocuprate(II), [CuBrnCl4−n]2− (n=0–4) anions and a tetraethylammonium cation has been studied using TG-FTIR, TG-MS, DTA and DTG techniques. The measurements were carried out in an argon and air atmospheres over the temperature range 293-1073 K. The products of the thermal decomposition were identified by IR and Far Infrared (FIR) spectroscopy as well as X-ray powder diffractometry.

Abstract  

Thermal decomposition of tetraethylammonium tetrachloro-, bromotrichloro-and tribromochloroferrates(III), of general formula [(C2H5)4N][FeBr4−nCln] (n=1, 3, 4), has been studied using the TG-MS, DTA and DTG techniques. The measurements were carried out in an argon atmosphere over the temperature range 293–1073 K. Solid products of the thermal decomposition were identified by Mössbauer spectroscopy.
