The thermal decomposition of the FeAc and FeAc-FD acetates (samples with mass around 9 mg contained in an alumina crucible) was studied by TGA/DSC techniques in a Netzsch thermal analyzer (model STA 409 PG/4/G Luxx) with synthetic air atmosphere ([N.sub.2] = 80% in flux of 40 mL/min.; [O.sub.2] = 20% in flux of 10 mL/min.).
Figure 1 shows the X-ray diffractograms for the acetates (FeAc and FeAc-FD).
