Ionic liquids (IL) attract major attention as advanced electrolytes, solvents and reaction control agents. However, up to date, their structure-property relationship remains mostly empirical. Despite being essentially a Coulomb-type system, in many aspects their properties are governed by weaker interactions – hydrogen bonding and even dispersion interactions. Although the Coulomb interaction is more than an order of magnitude stronger than the hydrogen bond, the local and directional nature of the hydrogen bond matters and influences characteristically the properties of these fluid salts. Normally, the formation of hydrogen bonds between cation and anion increases the attractive Coulomb interaction and tightens the interaction between the oppositely charged ions, resulting in preformation of ion-pairs, i.e. the (c-a) pairs.
