A nonheme FeNO}6 complex, [Fe(NO)(N3PyS)]2+, was synthesized by reversible, one‐electron oxidation of an FeNO}7 analogue. This complex completes the first known series of sulfur‐ligated FeNO}6–8 complexes. All three FeNO}6–8 complexes are readily interconverted by one‐electron oxidation/reduction. A comparison of spectroscopic data (UV/Vis, NMR, IR, Mössbauer, X‐ray absorption) provides a complete
通过FeNO} 7类似物的可逆单电子氧化合成非血红素FeNO} 6络合物[Fe(NO)(N3PyS)] 2+。该配合物完成了第一个已知的系列硫连接FeNO} 6-8配合物。所有三个FeNO} 6-8配合物都可以通过单电子氧化/还原而相互转化。光谱数据(UV / Vis,NMR,IR,Mössbauer,X射线吸收)的比较提供了FeNO} 6 – FeNO} 8互转换时发生的电子和结构变化的完整图片。NO与新的FeNO} 6的解离络合物受溶剂,温度和光解作用的控制,这对于硫键连接的FeNO} 6物种来说是罕见的。
