Abstract
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 the rNHCs and the N+ centre. Quantum chemical analysis established the presence of divalent NI character at the central nitrogen in these systems.
Remote N‐heterocyclic carbenes (rNHCs) are shown to coordinate to an N+ centre (see picture). Synthesis and characterization of some novel divalent NI complexes with the general formula (rNHC)→N←(NHC)+ and (rNHC)→N←(rNHC)+ is reported.
