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 ?-? stacking [centroid-centroid distances = 3.5518?(15)?Å] inter-actions.
