Potassium bis­[bis­(1-benzyl-3-methyl­imidazolium)silver(I)] tris­(hexa­fluoridophosphate)

In the title compound, K[Ag(C(11)H(12)N(2))(2)](2)(PF(6))(3), the 12-coordinate potassium cation lies on a crystallographic twofold axis and one of the hexa­fluoro­phosphate anions is generated by [Image: see text] symmetry. In the complex cation, the Ag(I) 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.
