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 N 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 the rNHCs and the N centre. Quantum chemical analysis established the presence of divalent N character at the central nitrogen in these systems.
远程 N-杂环卡宾（rNHCs），如 N-甲基-4-吡啶亚基，已知可与 TM 形成配位化合物。本文建立了 rNHCs 也可以与 N 中心配位的观点。合成了一些具有通式（rNHC）→N←（NHC）和（rNHC）→N←（rNHC）的新型二价 N 配合物，X 射线衍射研究支持 rNHCs 与 N 中心之间的配位键特征。量子化学分析确定了这些体系中中心氮上存在二价 N 特征。
