| Abstract: | The title complexes shown as Fe3O(C6H5COO)6(H2O)]Cl x 1.5H2O and Fe4O2 (C6H5COO)7(bipy)2]ClO4 x 3.5H2O were prepared. Their thermal decomposition process was studied qualitatively and quantitatively by means of thermogravimetric analysis and infrared spectroscopic measurement of samples after heating at different temperatures. From the experimental results, the possible thermal decomposition process of the two compounds can be deduced. Additionally, according to the fact that the nu(as) (COO) of the two compounds decreases while the nu(s) (COO) remains unchanged as the heating temperature increases. It can be drawn that the carboxylate coordinative form possible change from bridged to chelate one. |
