| 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 Na3CFe(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. |
