Remote N‐heterocyclic carbenes (rNHCs), such as N‐methyl‐4‐pyridylidene, are known to form coordination complexes with TMs. Herein, it is established that rNHCs can also coordinate to the N+ centre. Synthesis of some novel divalent NI complexes with the general formula (rNHC)→N+←(NHC) and (rNHC)→N+←(rNHC) was achieved, and X‐ray diffraction studies supported the coordination bond character between
远程N-杂环卡宾(r NHC),例如N-甲基-4-吡啶基,与TM形成配位配合物。在此,确定r个NHC也可以与N +中心协调。合成了一些具有通式(r NHC)→N + ←(NHC)和(r NHC)→N + ←(r NHC)的新型二价N I配合物,并且X射线衍射研究支持了配位键的特性在r NHC和N +中心之间。量子化学分析确定了二价N I的存在 这些系统中中心氮的特征。
