employment of lithium hexamethyldisilazide for the deprotonation
of methylene-bridged bis(imidazolium) salts led to the formation of
lithium carbene adducts. Depending on the crystallization method and
the substituents of the ligands, monomeric, dimeric, or polymeric
solid-state structures were obtained. These lithium carbene complexes
represent the first examples of lithium complexes bearing neutral
bis(N-heterocyclic carbene) ligands.
