3,3'-Dimethyl-1,1'-[(1,3-dihy-droxy-propane-2,2-di-yl)dimethyl-idene]diimidazolium bis-(hexa-fluoro-phosphate).

ABSTRACT: The title compound, C(13)H(22)N(4)O(2) (2+)·2PF(6) (-), was prepared by the anion exchange of the dibromide ionic liquid with potassium hexa-fluoro-phosphate. The two imidazole rings are each planar (r.m.s. deviations = 0.0016 and 0.0060 Å) and make a dihedral angle of 45.3 (18)°. Intra-molecular O-H⋯F hydrogen bonds occur. Inter-molecular C-H⋯F, O-H⋯O and C-H⋯O hydrogen bonds stabilize the crystal structure.
