A new synthetic method leading to N-heterocyclic carbene–silver(I) complexes [(R2-NHC)2Ag]+ [AgX2] is developed by using benzimidazolium compounds, NaOH (as a base), silver salts and water (as the reaction medium). Single-crystal X-ray structure revealed that compound 1 comprises a linear [Ag-(Et2-Bimy)2]+ cation and a linear [AgBr2] anion. These two ions are linked through an AgI–AgI association and staggered at an angle of 90.3°.
