Reaction between a carbazole-based mesoionic carbene ligand and manganese(II) iodide results in the formation of a rare air-stable manganese(IV) complex after aerobic workup. Cyclic voltammetry reveals the complex to be stable in five oxidation states. The electronic structure of all five oxidation states is elucidated chemically, spectroscopically (NMR, high-frequency EPR, UV-Vis, MCD), magnetically, and computationally (DFT, CASSCF).
咔唑基中氮茚卡宾配体与碘化锰（II）之间的反应，经有氧后处理后形成了一种罕见的空气稳定型锰（IV）配合物。循环伏安法表明该配合物在五种氧化态下均稳定。通过化学、光谱（核磁共振、高频电子顺磁共振、紫外可见光谱、磁圆二色光谱）、磁性和计算（密度泛函理论、完全活性空间自洽场）等方法阐明了所有五种氧化态的电子结构。
