description In the present work the synthesis, physicochemical characterization and thermoanalytical results of SrNh<SUB>4</SUB>[Fe(Cn)<SUB>6</SUB>] 3H<SUB>2</SUB>Oy BaNh<SUB>4</SUB>[Fe(Cn)<SUB>6</SUB>] are described. The thermal decompositions in oxygen atmosphere for both salts are carried out in the stages that lead to the formation of mixed oxides, i. e., SrFeO2.5 and BaFeO3-x at 1173 K. Barium carbonate is also obtained in the residue in the case of the decomposition of the barium complex. The total weight loss are 49,95% and 35,45 % for the strontium and barium salts, respectively. A decomposition mechanism is suggested for the pyrolisis processes from the data provided by IR spectroscopy, X-ray powder diffraction and chemical analysis. The specific surface area of the obtained oxides is also determined in order to evaluate its eventual catalytic activity.
