STUDIES ON SOLID STATE REACTIONS OF COORDINATION COMPOUNDS——XXIX. SOLID STATE SUBSTITUTION REACTIONS OF Nan [Fe(CN)5L]·mH2O WITH KCN
【摘要】 本文以Mossbauer谱为主要手段,配合气相色谱,热重等分析方法,研究了Nan,[Fe(CN)5L].mH2O(L=NH3,py,N2H5+,enH+)配合物与KCN固体,在100℃左右温度下发生的固相配位取代反应。指出反应是零级反应,按Id机理进行,配合物热分解脱去配体L的过程是决定步骤。
【Abstract】 The solid state substitution reaction of the coordination compoundsNan [Fe(CN)5L] · mH2O(L = NH3, py, N2H5+, enH + ) with KCN at about 100℃ was studied. The compound Na3 CFe(CN)5NH3]·3H2O was studied by Mossbauer in detail and chemical environment of iron atoms in the compound was described. The kinetics of the reaction was studied, the three rate constants at 3 different temperatures and activate energy were obtained. It was found that the reaction is of zero order and Td mechanism is inferred, elimination of the ligand being the rate determining step.
