固相配位化学反应研究ⅩⅩⅣ.一取代基五氰合铁(Ⅱ)类配合物热分解的质谱研究
摘要:
以四极质谱法为主要手段研究了一取代基五氰合铁(Ⅱ)类配合物在真空中的热分解,结合穆斯堡尔谱结果研究了固相物的化学组成,阐明了配合物的热分解机制,并发现配合物的热稳定性顺序与取代基团的光谱化学序列一致.对该类配合物的热分解动力学研究表明,分解活化能与分解峰值温度之间存在线性关系.

STUDIES ON THE SOLID STATE REACTION OF COORDINATION COMPOUNDS ⅩⅩⅣ.MASS SPECTROMETRIC INVESTIGATION OF THERMAL DECOMPOSITION OF PENTACYANOFERRATE(Ⅱ) COMPLEXES
Abstract:
The thermal decomposition of pentacyanoferratecomplexes Nax[Fe(CN)5L]·yH2O (L=NO+,N2H5+,enH+,NH3,H2O,pyridine,SO3) in vacuum has been investigated by quadrupole mass spectrometry as well as Mssbauer spectroscopy to detect the intermediate solid products during the decomposition.The mechanism of thermal decomposition is eluci-dated and it is found that the thermal stability of these complexes was ordered in accordance with the spectrochemieal series.Kinetic study on the decomposition showed that there is a linear relationship between the decomposition activation energies and the temperatures at which the ligand L lost.
