A tale of two carbenes : Reaction of :C[N(2,6‐ i Pr 2 C 6 H 3 )CH] 2 (IPr) with Mn 3 (mes) 6 (mes=2,4,6‐trimethylphenyl) yielded the trigonal planar complex [Mn(IPr)(mes) 2 ]. Reduction of this species with potassium/graphite in THF afforded the polymeric dicarbene‐bridged species K[{:C[N(2,6‐ i Pr 2 C 6 H 3 )] 2 (CH)C} 2 Mn(mes)(thf)]⋅THF (see picture). The anionic moiety in this complex is the first reported example of a transition metal complex containing an N‐heterocyclic dicarbene ligand. Gray C, blue N, red Mn.
