Dicyanoaurate(I) salts with 1-alkyl-3-methylimidazolium: luminescent properties and room-temperature liquid forming

Room-temperature ionic liquids containing dicyanoaurate(I) anions were prepared utilizing 1-alkyl-3-methylimidazolium cations, and display luminescence possibly due to the oligomerization of the significant fraction of Au(CN)(2) anions in the liquids.
