摘要
本文合成了氧心羧桥二种铁配合物:[Fe3O(C6H5COO)6(H2O)3]Cl和[Fe4O2(C6H5COO)7(bipy)2]ClO4,测定了它们的热失重及相应热效应峰值的红外光谱。根据不同温度下红外光谱基团的特征吸收峰的变化及热失重情况的分析。
The title complexes shown as [Fe 3O(C 6H 5COO) 6(H 2O) 3]Cl ·1 5H 2O and [Fe 4O 2(C 6H 5COO) 7(bipy) 2]ClO 4·3 5H 2O 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 ν as (COO) of the two compounds decreases while the ν 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.
