    ABSTRACT: The title compound, C13H22N4O22+center dot 2PF(6)(-), was prepared by the anion exchange of the dibromide ionic liquid with potassium hexafluorophosphate. The two imidazole rings are each planar (r.m.s. deviations = 0.0016 and 0.0060 angstrom) and make a dihedral angle of 45.3 (18)degrees. Intramolecular O-H center dot center dot center dot F hydrogen bonds occur. Intermolecular C-H center dot center dot center dot F, O-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds stabilize the crystal structure.

    ABSTRACT: The title compound, C12H20N42+·2BF4−, was prepared by the anion exchange of a dibromide ionic liquid with sodium tetrafluoroborate. The asymmetric unit contains one half of the imidazolium cation, which lies about an inversion centre at the mid-point of the central C—C bond of the linking butyl chain. The two planar imidazole rings (r.m.s. deviation = 0.0013 Å) are strictly parallel and separated by 2.625 (7) Å [vertical distance between the centroids of two imidazole rings], giving the molecule a stepped appearance. In the crystal structure, intermolecular C—H...F hydrogen bonds link the cations and anions, generating a three-dimensional network.
