| 摘要: 普鲁士蓝化合物的热分解过程,可分为三个阶段:(1)脱水;(2)Fe3+还原至Fe2+;(3)C≡N-键的断裂。H2气中的热分解由于发生了一系列的加氢反应,分解产物及所对应的分解温度都不同于He气中的情况,其产物的种类增加,C≡N-键的断裂温度降低。普鲁士蓝化合物中,CN-呈典型的双端基配位,可看作是一种双金属配位的活化模型,与CN-呈单端基配位的K3[Fe(CN)6]相比,C≡N-键的活化程度增加,不仅断裂温度降低,且能发生更深度的加氢反应。 |

| Abstract: Thermal decomposition process of Prussian blue may be divided into three steps: (1) dehydration,(2) reduction of Fe3+to Fe2+,and (3) rupture of the C≡N- triple bond. The species of decomposition products and the temperature corresponding to forming these products in hydrogen are different from those in helium,since a series of hydrogenation reactions take place in the former case,the species of decomposition products being more and the temperature at which the C≡N- triple bond breaks off being much lower. Prussian blue may be considered as a activation model of bimetal coordination since CN- acts as a typical biterminal ligand in it. In Prussian blue,the degree of activation of CN- is higher,the temperature at which the C≡N- triple bond breaks off lower and the degree of hydrogenation of CN-higher,in comparision with K3[Fe(CN)6] in which the CN- acts as a monoterminal lignd. |
