investigated in detail. A molybdenum(II) intermediate, K5[Mo(CN)7].N2H4, is isolated in the primary stage of the reaction that involves the oxidation of N2H4 to N2, as evidenced by the analysis of evolving gases. The powder X-ray crystal structure of K5[Mo(CN)7].N2H4 indicates the pentagonal bipiramidal geometry of the anion and the presence of N2H4 in proximity to the CN(-) ligands. The salt is characterized
详细研究了K4 [Mo(CN)8] .2 在98%N2H4.
H2O中的取代光解。如反应气体的分析所证明,在涉及N2H4氧化为N2的反应的主要阶段,分离出了一种
钼(II)中间体K5 [Mo(CN)7] .N2H4。K5 [Mo(CN)7] .N2H4的粉末X射线晶体结构指示阴离子的五边形双锥体结构,以及在CN(-)
配体附近存在N2H4。该盐的特征在于EDS,IR,UV-vis和EPR光谱以及循环伏安法测量。光解的第二阶段涉及将N2H4催化分解为NH3和N2,导致形成
钼(IV)络合物[Mo(CN)4O(NH3)] 2-。在光解的各个阶段,结合紫外可见光谱和EPR光谱测量对逸出气体的量进行监测,表明
钼(III,IV)对具有催化活性。介绍并讨论了
肼催化分解的方案。
