The title compound was prepared according to the reported procedures (Austin et al., 1981; Wei et al., 2008). Colourless single crystals suitable for X-ray diffraction were obtained by recrystallization from acetonitrile and ethyl ether (v:v = 1:1).
The structure was refined as an
with the final refined Flack factor being 0.50 (9). H-atoms were placed in calculated positions with C—H = 0.95–0.99 Å, and refined in the riding mode with Uiso(H) = 1.2Ueq(C).Since the first free carbene was isolated by (Arduengo et al., 1991), N-heterocyclic carbene (NHC) ligands have gradually take up important roles in organometallic chemistry (Lin et al., 2009). Herein we report on the
of the title N-heterocyclic carbene compound.The molecular structures of the two independent N-heterocyclic carbene dications (cation A and cation B) are illustrated in Fig. 1. The bond lengths (Allen et al., 1987) and angles are within normal ranges. In the cations the benzene rings make dihedral angles of 88.82 (16) ° in cation A and 87.03 (16) ° in cation B. The imidazole rings are twisted with respect to the attached benzene rings being inclined to one another by 35.7 (2)° and 32.83 (18)° in cation A and 30.14 (19)° and 31.96 (18)° in cation B.
In the crystal there is an extensive arrangement of C—H···F hydrogen bonds, which not only stabilizes the molecular structure but also link the cations (Table 1 and Fig. 2) to form a three-dimensional network. There are also π–π interactions involving rings N3/C18/N4/C19/C20 and C26—C31 [symmetry code: x, y, z], with the ring centroids being separated by 3.602 (2) Å, and rings C5-C10 and N7/C39/N8/C40/C41 [symmetry code: x, y+1, z] with ring centroids separated by 3.723 (2) Å. In addition C—H···π interactions, involving the imidazole and benzene rings, are also present (Table 1).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell esds are taken into account in the estimation of distances, angles and torsion angles |
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 > 2sigma(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. |

Since the first free carbene was isolated by (Arduengo et al., 1991), N-heterocyclic carbene (NHC) ligands have gradually take up important roles in organometallic chemistry (Lin et al., 2009). Herein we report on the crystal structure of the title N-heterocyclic carbene compound.
The molecular structures of the two independent N-heterocyclic carbene dications (cation A and cation B) are illustrated in Fig. 1. The bond lengths (Allen et al., 1987) and angles are within normal ranges. In the cations the benzene rings make dihedral angles of 88.82 (16) ° in cation A and 87.03 (16) ° in cation B. The imidazole rings are twisted with respect to the attached benzene rings being inclined to one another by 35.7 (2)° and 32.83 (18)° in cation A and 30.14 (19)° and 31.96 (18)° in cation B.
In the crystal there is an extensive arrangement of C—H···F hydrogen bonds, which not only stabilizes the molecular structure but also link the cations (Table 1 and Fig. 2) to form a three-dimensional network. There are also π–π interactions involving rings N3/C18/N4/C19/C20 and C26—C31 [symmetry code: x, y, z], with the ring centroids being separated by 3.602 (2) Å, and rings C5-C10 and N7/C39/N8/C40/C41 [symmetry code: x, y+1, z] with ring centroids separated by 3.723 (2) Å. In addition C—H···π interactions, involving the imidazole and benzene rings, are also present (Table 1).
