Remote N‐heterocyclic carbenes ( r NHCs), such as N ‐methyl‐4‐pyridylidene, are known to form coordination complexes with TMs. Herein, it is established that r NHCs can also coordinate to the N + centre. Synthesis of some novel divalent N I complexes with the general formula ( r NHC)→N + ←(NHC) and ( r NHC)→N + ←( r NHC) was achieved, and X‐ray diffraction studies supported the coordination bond character between the r NHCs and the N + centre. Quantum chemical analysis established the presence of divalent N I character at the central nitrogen in these systems.
