Ionic Liquids or ILs are organic salts which are in liquid state at room temperature. This particular behavior can be ascribed to the poor coordination of their constituent ions, since at least one of them has a delocalized charge preventing the formation of a stable crystal lattice. ILs consists of large organic cations like quaternary ammonium, imidazolium or pyridinium ions combined with anions of smaller size and more symmetrical shape such as Cl−, Br−, I−, AlCl−4, BF−4, PF−6, ROSO−3, trifluoromethanesulfonate and others...... Enough??

Thanks Dr Faheem Shah.

An ionic liquid is a salt in which the ions are poorly coordinated, which results in these solvents being liquid below 100°C, or even at room temperature (room temperature ionic liquids, RTIL's). At least one ion has a delocalized charge and one component is organic, which prevents the formation of a stable crystal lattice.

You are welcome...

Ionic liquids are molten salts at room temperature. The main advantage of an ionic liquid is that it practically exerts no vapor pressure while offering the benefits of conventional solvents that have high volatility. They are

aprotic and their properties, such as viscosity, melting point, density, and hydrophobicity, may be modified to meet the desired conditions by variation in the cations and anions.

Thanks Ms Kamakshi

what i need is . Define Ionic Liquids?

Kamakshi R.  I thought Aprotic ionic liquids are another subset of ionic liquids not their property. Correct me if i am wrong.

Dear All,

Any database for ionic liquid for downloading 3D molecule file.

Thank You All

An ionic liquids are salts in the liquid state , poor conductors of electricity, non-ionizing, highly viscous and frequently exhibit low vapor pressure . They contain bulky and asymmetric organic cations such as 1-alkyl-3-methylimidazolium, 1-alkylpyridinium, N-methyl -N- alkylpyrrolidinium and ammonium ions.
