摘要

我们报告了[Co(NH3)5NO2]2I3Cl 的不寻常连接光异构化现象。在可见光照射下，[Co(NH3)5NO2]2+ → [Co(NH3)5ONO]2+反应只发生在特定晶体学位置的配合阳离子上。通过对试剂和产物的晶体结构和红外光谱的详细分析，我们分析了这一特征，它表明在同一晶体结构中反应性的 "晶体学控制"。

Unusual linkage photoisomerization in [Co(NH3)2NO2]2I3Cl single crystals†

We report the unusual linkage photoisomerization for [Co(NH₃)₅NO₂]₂I₃Cl. The reaction [Co(NH₃)₅NO₂]²⁺ → [Co(NH₃)₅ONO]²⁺ occurs upon irradiation by visible light for complex cations in certain crystallographic positions only. This feature, suggesting “crystallographic control” of reactivity within the same crystal structure, has been analysed via detailed analysis of crystal structures and IR spectra of the reagent and product.
