Thermodynamically Stable Cationic Dimers in Carboxyl-Functionalized Ionic Liquids: The Paradoxical Case of “Anti-Electrostatic” Hydrogen Bonding

We show that carboxyl-functionalized ionic liquids (ILs) form doubly hydrogen-bonded cationic dimers (c(+)=c(+)) despite the repulsive forces between ions of like charge and competing hydrogen bonds between cation and anion (c(+)–a(−)). This structural motif as known for formic acid, the archetype o...
