title: Potassium bis-[bis-(1-benzyl-3-methyl-imidazolium)silver(I)] tris-(hexa-fluoridophosphate).
abstract: 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 hexa-fluoro-phosphate anions is generated by 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-methyl-imidazolium units, the dihedral angles between imidazolium and phenyl rings are 80.47 (15) and 76.53 (14)°. The F atoms of the general-position hexa-fluoro-phosphate anion are disordered over two sets of sites in a 0.767 (17):0.233 (17) ratio. In the crystal, the hexa-fluoro-phosphate anions link the cations into three-dimensional networks via inter-molecular C-H⋯F hydrogen bonds and are further consolidated by π-π stacking [centroid-centroid distances = 3.5518 (15) Å] inter-actions.
