New families of salts viz. quaternary ammonium, N-alkyl-N-methylpyrrolidinium or 1-alkyl-3- methylimidazolium dicyanamides, Cat+ N (CN) 2−, are low melting compounds, most being liquid at rt, water-miscible and have low (for ionic liquids) viscosity at rt, eg η= 21 cP for 1- ethyl-3-methylimidazolium dicyanamide.
