The 1,3‐bis(tricyanoborane)imidazolate anion  1  was obtained in high yield from lithium imidazolate and B(CN) 3 −pyridine adduct. Anion  1  is chemically very robust and thus allowed the isolation of the corresponding H 5 O 2  +  salt. Furthermore, monoanion  1  served as starting species for the novel dianionic N‐heterocyclic carbene (NHC), 1,3‐bis(tricyanoborane)imidazoline‐2‐ylidenate anion  3  that acts as ditopic ligand via the carbene center and the cyano groups at boron. First reactions of this new NHC  3  with methyl iodide, elemental selenium, and [Ni(CO) 4 ] led to the methylated imidazolate ion  4 , the dianionic selenium adduct  5 , and the dianionic nickel tricarbonyl complex  6 . These NHC derivatives provide a first insight into the electronic and steric properties of the dianionic NHC  3 . Especially the combination of properties, such as double negative charge, different coordination sites, large buried volume and good σ‐donor and π‐acceptor ability, make NHC  3  a unique and promising ligand and building block.
