Source of material
Silver perchlorate (118.7 mg, 0.57 mmol) was placed in 15 ml of water at room temperature. A 30 ml DMF solution containing 1,3-bis(octyl)benzimidazolium chloride (252 mg, 0.57 mmol) was added and the mixture stirred for 3 h. The white mixture obtained was extracted and cooled to room temperature. The precipitate was removed and the filtrate was evaporated to dryness to obtain colourless crystals.
Experimental details
The perchlorate anion was found to be disordered over two positions [0.590(14) : 0.410(14) occupancies]. One of the octyl side chains was also found to be disordered [0.704(8) : 0.296(8)]. Hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms.
Comment
Ionic liquids are liquids composed entirely of ions. They are usually defined as ionic compounds which are liquid below the boiling point of water and are composed of a larger organic cation and a smaller inorganic anion [4]. Alongside the more common so-called room-temperature ionic liquids, molten salts with melting points between – 50 and 200 °C are sometimes also considered as ionic liquids [5]. Ionic liquids are widely used in catalysis and material chemistry [6], [7], [8].
The title compound, whose melting point has not been measured, is based on the benzimidazolium cation, which is a fairly common building block for ionic liquids. In the crystal structure, the cations form a U-shaped structure that looks like a two legged pincer. The two alkyl chains linked to the benzimidazole moiety are almost perpendicular to the aromatic ring. The N9 C8 C7 and N11 C18A C19A angles are 112.0(2)° and 111.3(3)°, respectively. In the crystal structure there are aromatic interactions between stacked dimers of cations that give rise to large hydrophobic slabs containing the long alkly chains, with the anions occupying the space between these slabs.
