The title mol­ecular salt, C6H11N2O2+·C2F6NO4S2−, was obtained by the methyl­ation of 1-hy­droxy-2-methyl­imidazole 3-oxide and subsequent ion metathesis. In the crystal, C—H⋯O=S hydrogen bonds and O⋯π inter­actions are observed.

Structure description

The mol­ecular structure of the title compound is shown in Fig. 1[link]. The ions which build this salt, both 1,3-di­alkyl­oxyimidazolium cations (Laus et al., 2010[Laus, G., Wurst, K., Kahlenberg, V., Kopacka, H., Kreutz, C. & Schottenberger, H. (2010). Z. Naturforsch. Teil B, 65, 776-782.]) and the bis­(triflimide) anion (Bentivoglio et al., 2009[Bentivoglio, G., Schwärzler, A., Wurst, K., Kahlenberg, V., Nauer, G., Bonn, G., Schottenberger, H. & Laus, G. (2009). J. Chem. Crystallogr. 39, 662-668.]; Laus et al., 2011[Laus, G., Hummel, M., Többens, D. M., Gelbrich, T., Kahlenberg, V., Wurst, K., Griesser, U. J. & Schottenberger, H. (2011). CrystEngComm, 13, 5439-5446.]), are known to exist as syn/anti conformers in the solid state. Thus, the meth­oxy substituents of the cation adopt an anti conformation with a C5—O1⋯O2—C6 torsion angle of 170.6 (4)°. The bis­(triflimide) anion also assumes an anti conformation with a C7—S1⋯S2—C8 torsion angle of 174.9 (2)°. Each cation donates three C—H⋯O=S hydrogen bonds to three anions (Fig. 2[link]). The hydrogen-bond parameters are summarized in Table 1[link]. An intriguing inter­molecular inter­action between atom O3 of the anion and the π system of the imidazolium ring is observed. The pertinent O3⋯Cg distance is 2.971 Å, where Cg is the centroid of the heterocyclic ring. This inter­action is directional with an S1=O3⋯Cg angle of 152°. The crystal packing is shown in Fig. 3[link].

The cation in the structure of the related 1,3-dimeth­oxy-2-methyl­imidazolium tris­(penta­fluoro­eth­yl)tri­fluoro­phosphate displayed a syn geometry (Laus et al., 2007[Laus, G., Schwärzler, A., Schuster, P., Bentivoglio, G., Hummel, M., Wurst, K., Kahlenberg, V., Lörting, T., Schütz, J., Peringer, P., Bonn, G., Nauer, G. & Schottenberger, H. (2007). Z. Naturforsch. Teil B, 62, 295-308.]). Anion⋯π inter­actions have been observed in related imidazolium salts (Froschauer et al., 2012[Froschauer, C., Kahlenberg, V., Laus, G. & Schottenberger, H. (2012). Crystals, 2, 1017-1033.]).

Synthesis and crystallization

A suspension of 1-hy­droxy-2-methyl­imidazole-3-oxide (5.09 g, 44.6 mmol) and dimethyl sulfate (9.0 ml, 100 mmol) in H2O (5.0 ml) was stirred at room temperature for 30 min. Calcium carbonate (6.35 g, 63.4 mmol) and H2O (6.0 ml) were then added to the slurry, and a slight increase of temperature was observed. The mixture was stirred for 15 h. Then hydro­chloric acid (36%; 11.0 ml, 129.2 mmol) was added in portions and stirred for 2 h, resulting in a clear solution. Lithium bis­(tri­fluoro­methane­sulfon­yl)imide (13.0 g, 44.9 mmol) was added, whereupon crystallization of the product occurred. After stirring for 1 h, the mixture was extracted with CH2Cl2 (3 × 50 ml). The combined organic phases were then washed with H2O (100 ml) and dried over Na2SO4. The solvent was removed under reduced pressure, and the product was dried at 75°C in vacuum (< 1 mbar). On cooling to room temperature the product was obtained as a colourless crystalline solid (yield 97%), mp. 66°C.

The molecular structure of the title compound is shown in Fig. 1. The ions which build this salt, both 1,3-dialkyloxyimidazolium cations (Laus et al., 2010) and the bis(triflimide) anion (Bentivoglio et al., 2009; Laus et al., 2011), are known to exist as syn/anti conformers in the solid state. Thus, the methoxy substituents of the cation adopt an anti conformation with a C5—O1···O2—C6 torsion angle of 170.6 (4)°. The bis(triflimide) anion also assumes an anti conformation with a C7—S1···S2—C8 dihedral angle of 174.9 (2)°. Each cation donates three C—H···O═S hydrogen bonds to three anions (Fig. 2). The hydrogen bond parameters are summarized in Table 1. An intriguing intermolecular interaction between O3 of the anion and the π system of the imidazolium ring is observed. The pertinent O3···Cg distance is 2.971 Å, where Cg is the centroid of the heterocyclic ring. This interaction is directional with a S1═O3···Cg angle of 152°, and the crystal packing is shown in Fig. 3.

The cation in the structure of the related 1,3-dimethoxy-2-methylimidazolium tris(pentafluoroethyl)trifluorophosphate displayed the syn geometry (Laus et al., 2007). Anion···π interactions have been observed in related imidazolium salts (Froschauer et al., 2012).

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
