In the title compound, K[Ag(C11H12N2)2]2(PF6)3, the 12-coordinate potassium cation lies on a crystallographic twofold axis and one of the hexafluorophosphate anions is generated by symmetry. In the complex cation, the AgI ion is coordinated by two C atoms; the two imidazolium rings are orientated at a dihedral angle of 8.14 (14)°. In the 1-benzyl-3-methylimidazolium units, the dihedral angles between imidazolium and phenyl rings are 80.47 (15) and 76.53 (14)°. The F atoms of the general-position hexafluorophosphate anion are disordered over two sets of sites in a 0.767 (17):0.233 (17) ratio. In the crystal, the hexafluorophosphate anions link the cations into three-dimensional networks via intermolecular C—H⋯F hydrogen bonds and are further consolidated by π–π stacking [centroid–centroid distances = 3.5518 (15) Å] interactions.

To a stirred solution of 1-benzyl-3-methylimidazolium hexafluorophosphate (0.5 g, 1.57 mmol) in acetonitrile (40 ml), Ag2O (0.37 g, 1.6 mmol) was added. The mixture was refluxed at 70 °C for 18 h in glassware wrapped in aluminum foil to exclude the light. The mixture was filtered through celite to remove excess Ag2O and the solvent was evaporated under vacuum. The white residue was washed with diethyl ether (2 × 3 ml) to afford the complex as a white powder, the yield was 0.66 g, 70.3%, m. p. = 421-423 K. Colourless blocks of (I) were obtained by slow diffusion of diethyl ether into a solution of the complex in acetonitrile at ambient temperature.
All H atoms were positioned geometrically and refined using a riding model with C–H = 0.93-0.97 Å and Uiso(H) = 1.2 or 1.5 Ueq(C). A rotating-group model was applied for the methyl groups. Six fluorine atoms (F1A-F6A) of the hexafluorophosphate anion are disordered over two positions with refined site-occupancies of 0.767 (17) : 0.233 (17). The minor component of disorder was refined isotropically and subjected to rigid bond and similarity restraints. The highest residual electron density peak is located at 0.82 Å from Ag1 and the deepest hole is located at 0.69 Å from Ag1.
Metal complexes of
based on imidazol-2-ylidene have received much attention in the past few years (Lee et al., 2001). A major reason is that these N-heterocyclic carbenes(NHCs) can stabilize both high and low metal ions and form stable complexes with a wide range of metals (Bourissou et al., 2000; Herrmann & Köcher, 1997; Hermann et al., 1996). Among these complexes, the family of silver NHC complexes have been receiving continuous attention (Zhou et al., 2008). The in-situ deprotonation method using Ag2O as a basic metal source developed by Lin and co-workers (Wang & Lin, 1998) has been widely employed to synthesise these Ag-NHC complexes. The silver complexes act as effective carbene transfer agents to other metals and are much more stable than the free carbene (Lin & Vasam, 2007). Biological activity of many Ag-NHC complexes as antimicrobial and antitumour agents has been confirmed (Ray et al., 2007; Özdemir et al., 2010; Medvetz et al., 2008).The
of the title compound, (I), contains a bis(1-benzyl-3-methylimidazolium)silver(I) cation, a K cation and one and a half hexafluorophosphate anions (Fig. 1). The two imidazolium rings (N1/N2/C1-C3 and N3/N4/C12-C14) make a dihedral angle of 8.14 (14)°, indicating that they are almost parallel to each other. In the two 1-benzyl-3-methylimidazolium moieties [N1/N2/C1-C11 (A) and N3/N4/C12-C22 (B)], the dihedral angles between imidazolium and phenyl rings are 80.47 (15) and 76.53 (14)° in A and B, respectively. The P2 atom of the hexafluorophosphate anion is lying on a crystallographic inversion center (symmetry code: -x, -y, -z) whereas the 12-coordinate potassium cation (Fig. 2) lies on a crystallographic twofold axis (symmetry code: -x, y, -z+1/2). Six fluorine atoms (F1A-F6A) of the hexafluorophosphate anion are disordered over two positions with refined site-occupancies of 0.767 (17) : 0.233 (17). Bond lengths and angles are within normal ranges, and comparable to closely related structures (Haque et al., 2010a,b)In the π-π stacking interactions between N1/N2/C1-C3 (centroid Cg1) and N3/N4/C12-C14 (centroid Cg2) rings, with a Cg1···Cg2 distance of 3.5518 (15) Å.
(Fig. 3), the hexafluorophosphate anions link the cations into three-dimensional networks via intermolecular C14–H14A···F1, C15–H15A···F6, C15–H15BA···F4 and C22–H22A···F6 hydrogen bonds (Table 2) and are further consolidated byFor general background to and the biological activity of carbene derivatives, see: Lee et al.

Experimental. The crystal was placed in the cold stream of an Oxford Cyrosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K. |
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. |
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. |

Metal complexes of carbenes based on imidazol-2-ylidene have received much attention in the past few years (Lee et al., 2001). A major reason is that these N-heterocyclic carbenes(NHCs) can stabilize both high and low oxidation state metal ions and form stable complexes with a wide range of metals (Bourissou et al., 2000; Herrmann & Köcher, 1997; Hermann et al., 1996). Among these complexes, the family of silver NHC complexes have been receiving continuous attention (Zhou et al., 2008). The in-situ deprotonation method using Ag2O as a basic metal source developed by Lin and co-workers (Wang & Lin, 1998) has been widely employed to synthesise these Ag-NHC complexes. The silver complexes act as effective carbene transfer agents to other metals and are much more stable than the free carbene (Lin & Vasam, 2007). Biological activity of many Ag-NHC complexes as antimicrobial and antitumour agents has been confirmed (Ray et al., 2007; Özdemir et al., 2010; Medvetz et al., 2008).
The asymmetric unit of the title compound, (I), contains a bis(1-benzyl-3-methylimidazolium)silver(I) cation, a K cation and one and a half hexafluorophosphate anions (Fig. 1). The two imidazolium rings (N1/N2/C1-C3 and N3/N4/C12-C14) make a dihedral angle of 8.14 (14)°, indicating that they are almost parallel to each other. In the two 1-benzyl-3-methylimidazolium moieties [N1/N2/C1-C11 (A) and N3/N4/C12-C22 (B)], the dihedral angles between imidazolium and phenyl rings are 80.47 (15) and 76.53 (14)° in A and B, respectively. The P2 atom of the hexafluorophosphate anion is lying on a crystallographic inversion center (symmetry code: -x, -y, -z) whereas the 12-coordinate potassium cation (Fig. 2) lies on a crystallographic twofold axis (symmetry code: -x, y, -z+1/2). Six fluorine atoms (F1A-F6A) of the hexafluorophosphate anion are disordered over two positions with refined site-occupancies of 0.767 (17) : 0.233 (17). Bond lengths and angles are within normal ranges, and comparable to closely related structures (Haque et al., 2010a,b)
In the crystal structure, (Fig. 3), the hexafluorophosphate anions link the cations into three-dimensional networks via intermolecular C14–H14A···F1, C15–H15A···F6, C15–H15BA···F4 and C22–H22A···F6 hydrogen bonds (Table 2) and are further consolidated by π-π stacking interactions between N1/N2/C1-C3 (centroid Cg1) and N3/N4/C12-C14 (centroid Cg2) rings, with a Cg1···Cg2 distance of 3.5518 (15) Å.
