We report the synthesis and characterization of a new
anionic pincer-type
μ2-η2(1κCcarbene:2κC′carbene)–C*–N–C*)
ligand with a triazine core. Hydrolysis of one chloro substituent
of the cyanuric chloride leads to the hydroxy-2,4-dichloro-1,3,5-triazine
and the corresponding bis(imidazolium) salts, which, after deprotonation,
serve as monoanionic ligands. Treatment of the bis(imidazolium) precursor
with silver(I) oxide leads to stable silver(I)–NHC complexes
with interesting photophysical properties (phosphorescent emission
in the deep blue region of the spectrum). Depending on the substitution
pattern of the NHC ligand, the emission can be shifted between 417
and 480 nm. X-ray structure analysis reveals the dimeric structure
of these complexes.
