In the title salt, C11H21N2+·C6H5O3S−, which has two cation–anion pairs in the the two imidazolium cations are linked to two separate acceptor O atoms of one of the benzenesulfonate anions through aromatic C—H⋯O hydrogen bonds, while the second anion is unassociated.

The title compound was prepared by slow addition of benzenesulfonic acid (0.425 g, 2.67 mmol) to a solution containing 0.481 g (2.67 mmol) of 1,3-diisopropyl-4,5-dimethyl-4,5-dimethylimidazol-2-ylidene (see Kuhn & Kratz, 1993), in 20 ml of dry Et2O at -25° C. After stirring overnight at room temperature, the precipitate was filtered off, washed with dry Et2O and dried under reduced pressure. Yield: 0.814 g (90%). This solid was recrystallized from CH3COCH3/ Et2O as colorless crystals.
Hydrogen atoms were included in the
at calculated positions and some were allowed to refine isotropically while the remainder were included at calculated positions with C—H = 0.95–1.00 Å and with Uiso(H) = 1.2Ueq(aromatic C) or 1.5Ueq(aliphatic C), using a riding-model approximation.Data collection: X-AREA (Stoe & Cie, 2008); cell

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Due to the strongly basic character of N-heterocyclic carbenes, their reactions with acidic compounds usually produce 2H-imidazolium cation pairs. The formation of stable C—H···O bonds between the components of these compounds may act as an additional stabilizing factor in their crystal structures (Kuhn et al., 2007). The structures have shown that these pairs are linked by imidazolium aromatic C—H···O hydrogen bonds as observed commonly in imidazolium salts (Sweidan et al., 2009). However, the crystal structure of 1,3-di-tert-butyl-4,5-dimethylimidazolium trifluoromethanesulfonate showed the absence of intermolecular hydrogen bonding between the imidazolium cation and the trifluoromethanesulfonate anion (Grishina et al., 2011).
The structure of the title compound, C11H21N2+ C6 H5O3S- (Fig. 1), which has two cation–anion pairs in the asymmetric unit, reveals the presence of intermolecular aromatic C—H···Osulfonate hydrogen-bonding interactions between the two imidazolium cation moieties and two separate oxygen atoms of one of the benzenesulfonate anion moieties (Table 1, Fig. 1). Surprisingly, the second anion is not involved in any intermoleculer hydrogen bonding, which may be attributed to the steric crowding effect of the cation ring.
